Android Support Page


All apps require Android 4.x

IMPORTANT:
BEFORE installing apps aMCA or ExtCam,
please install/run app OTG Status to see
if your phone/tablet CAN run them.

App support:
This support page should handle 99% of all issues; if you still have problems after going through this page, first read the disclaimer at the bottom of this page. If appropriate, send an email to therau2000@videotron.ca and make sure to specify:
  • your full name;
  • your location (country);
  • phone/tablet make and model;
  • Android version;
  • kernel and version;
  • app(s) installed and version(s);
  • clear description of problem, including screen snapshot(s) as required.
Quick start:
Detailed information:
  1. No Android device yet ?
  2. Most Annoying Issues with Android 4.3
    • Frequent intermittent USB problems
      • Host USB does not work correctly unless Android 4.3 initial setup is done in the default language: English (United States); when Android 4.3 initial setup is not done in English US, USB behaviour is mostly unpredictable/unreliable. See this page and this page for details.
      • Host USB may start/stop working for no apparent reason after several reboots.
      • Disabling Auto-rotate screen in Accessibility seems to improve the situation a little bit.
      • Always connect/disconnect OTG cable every time camera is connected/disconnected.
      • It may take 20 (or more) connect/disconnect for Mobius camera to be recognized. This may be related to USB cables; see Quick Start above.
      • Mobius camera stops being recognized for no apparent reason; it may be recognized again after several reboots.
    • Any app can crash for no reason
      • The crash always happens in the OS code, right after allocating memory; apparently allocated memory was already in use. System app Settings seems to crash more often than any other.
      • Solution:
        • there is no known solution to this problem, except maybe updating the OS to a more recent version.
    • App no longer opens automatically
      • When connecting Camera, installed app used to always open automatically; now nothing happens when connecting Camera.
      • Solutions:
        • For aMCA, use the manual launcher that is now available.
        • use Settings, Apps, select the app then scroll down to the bottom and, under LAUNCH BY DEFAULT, touch Clear defaults; it sometimes clears this problem.
        • uninstall and reinstall app from Play Store; it sometimes clears this problem.
        • rebooting your device several time may help clear this problem.
    • "Damaged USB storage" error when connecting Camera (also seen on Android 4.1 and 4.2)
      • This problem can happen when connecting a Camera that has a low or nearly depleted battery.
  3. Before installing aMCA/ExtCam apps:
    • It is of critical importance that both Steps 1 and 2, described in these instructions, do work perfectly.
      • Typical reasons for Step 1 failures:
        • Defective USB OTG adapter cable/plug. Replace USB OTG adapter.
        • Android Device does not support Host USB feature. STOP; the apps will never work on this device.
      • Typical reasons for Step 2 failures:
        • Device cannot support USB Mass Storage mode.
        • Defective/intermittent USB OTG adapter cable/plug. Replace USB OTG adapter.
        • The Android device is not able to supply enough power to the camera to power its USB interface; low or discharged or defective battery.
        • "High power USB device detected" error condition detected but never properly cleared (see General Information: below).
      • Note: Based on current battery condition, an Android device will never put itself in danger by providing more USB power than it can reasonably supply to any external device. It will simply ignore the USB device.
    • Possible solutions:
      1. Replace Android device's battery with a fully charged brand new battery.
      2. Use a USB OTG adapter with external power.
      3. Android device may be defective; repair or replace.
    • When Step 2 fails for any reason, there is no point in installing any app until the specific problem is resolved. The apps would not work anyway and the apps would not be at fault.
  4. App Installation:
    • Requirement:
      • Phone/tablet running Android 4.x and supporting the Host USB feature.
      • Connect Camera to Android device using both a USB Type A Male to Mini-USB Type B Male Adapter and a USB OTG adapter cable/plug (except on tablets equipped with a Type-A female USB receptacle where a USB OTG adapter is not required).
    • All Android apps have been designed and built to work with standard un-modified Android 4.x OS and do not require root or any modification to your Android device.
    • All Android apps need to be updated at least once a month to ensure everyone uses the most recent version of the app; this frees up support hours to further develop apps. Enable Automatic Update for trouble-free app updates.
    • If you sign-in to Play Store on your computer and select one of these apps and get a message saying something like "This app is not compatible with your device." see next item.
    • If your device does support Host USB (as per new app app OTG Status) but you cannot see these apps in Play Store on your phone/tablet, it is most likely due to missing USB authorizations (a common problem with less expensive tablets); follow Step 3 of these instructions to correct the situation.
    • If you can see an app in Play Store and install it on your phone/tablet, then it should run on your device; all you need are 2 adapters: USB Type A Male to Mini-USB Type B Male adapter and USB OTG adapter cable/plug (except for tablets equipped with a Type-A female USB receptacle where a USB OTG adapter is not required).
    • If you have a Mobius ActionCam, install apps with the Mobius Logo:
    • If you have a #16 camera, install apps with the #16 Logo:
    • In Play Store, all apps are not available in all countries.
    • If an app does not run at all on your phone/tablet for one reason or another, don't rate it !
  5. App does not open when connecting camera:
    • By design, the apps are never at fault if they don't open automatically, so don't blame the apps.
    • Always power on camera and wait until yellow LED is on before connecting camera to phone/tablet.
    • After installing an app, the first time you connect a Mobius ActionCam or #16 camera, you should see a USB Authorization request like this for aMCA or like that for ExtCam. Touch Always or put a check mark where indicated and touch OK. From that point on, the app will open automatically when you connect camera (overriding the File Browser if one opens automatically).
      • Note: On some devices (e.g. Samsung), a file browser 'MyFiles' opens automatically when connecting a camera with its SD card inserted. If any app (other than aMCA or ExtCam) opens automatically, DO NOT touch the Home button because it will cancel the USB Authorization request ! DO repeatedly touch the Return button until that app (e.g. the file browser) closes. You will then see the USB Authorization request.
    • The OS is 100% responsible for launching the correct app when a camera is connected (using app setup information provided by the app at install time):
      • SD card inserted in camera = configuration mode = aMCA;
      • SD card removed from camera = WebCam mode = ExtCam.
    • If you install more than one app providing the same type of functionality, you will be presented a USB authorization request like this; do not touch Always or put a check mark otherwise the other app will not be available, even if it is still installed. If you did touch Always or put a check mark and want to change your choice, use Settings, Apps, select the app then scroll down to the bottom and, under LAUNCH BY DEFAULT, touch Clear defaults.
    • App (aMCA and/or ExtCam) used to open automatically, but no longer opens when connecting camera; observed mostly on Android 4.3. This is an OS launcher problem that has nothing to do with the app; there are 2 solutions that have been used with success:
      • aMCA only: use the manual launcher now available; if that does not work, it is most likely because the OS is ignoring all USB devices due to a "High power USB device detected" error condition (see 'General Information:' below);
      • clear default launcher settings as follows: use Settings, Apps, select the app then scroll down to the bottom and, under LAUNCH BY DEFAULT, touch Clear defaults and proceed as if the app has just been installed;
      • un-install then re-install the app and proceed as explained at the beginning of this section.
    • Because the apps are open automatically by the OS, there is no way to launch them manually; that is why they have no launcher icon (also called invisible app). There was an app with manual open (aMCA Basic - it was discontinued on 2013-06-15); hundreds of people installed it and then un-installed it to install aMCA. Fully automatic apps are what 99% of people want.
    • The app is responsible for closing itself when camera is disconnected, but the OS is 100% responsible for launching it. If the app does not open automatically, the app is not at fault;
      • if the app never opens automatically, it is most likely because another app claimed the camera's removable drive. The solution is to find that other app (most often Nexus Media Importer, Nexus Photo Viewer, StickMount, USB Stick Plugin-TC, or similar apps) then, use Settings, Apps, select that other app, then scroll down to the bottom and, under LAUNCH BY DEFAULT, touch Clear defaults.
      • if the app sometimes opens automatically but sometimes does not, it is probably because the OS is ignoring the camera connection due to low batteries - either in phone/tablet and/or camera. This usually triggers a "High power USB device detected" error condition, but not always. In any case, this error condition can easily be missed.
  6. General Information:
    • On most phones/tablets, the only way to clear a "High power USB device detected" error condition is to power-off, fully charge battery (of phone/tablet) and power-on device; sometimes a Restart is also required. Most phones/tablets will ignore all USB connections until the error condition is cleared.
    • When in doubt, always charge both your phone/tablet battery and camera battery to avoid intermittent problems caused by low batteries.
    • From the app's perspective, a V1 #16 camera and a V2 #16 camera are both identical.
    • From the app's perspective, a pre-release and a release Mobius ActionCam are both identical.
    • USB/OTG Helper apps are not required; they often interfere with normal USB operation.
  7. aMCA/aMCA Mobius AC:
    • These apps do not have a File Browser; when you touch Browse SD, apps exit to allow you to browse files. On some phone/tablets (e.g. Samsung), a File Browser opens automatically. In any case, you are responsible to manually close the File Browser and unmount camera's removable drive before disconnecting camera.
    • #16V3 and Mobius ActionCam only: Make sure to set "Charge from USB Host" to "off" to avoid draining your Android device's battery.
  8. ExtCam #16 HD/ExtCam Mobius AC HD:
    • ExtCam Mobius AC HD was designed specifically to work in HD with the Mobius ActionCam; other cameras are not supported.
    • ExtCam #16 HD was designed specifically to work in HD with the #16 camera; other cameras are not supported.
    • ExtCam apps are CPU/Memory intensive apps that work best on devices with multi-core CPUs.The OS will shut them down if they take too many resources.
    • Immediately after power on, the OS is very busy with updates and will stop any app that uses resources needed for system processes to run. The OS can therefore shut down the app and display "THE APPLICATION HAS TURNED OFF".
    • After powering on your Android device, it is best to wait at least a couple of minutes before connecting a camera in WebCam mode.
    • These apps record video in the MJPEG/AVI format. Frame indexing is optional in this video format; it is not created for performance reasons.
    • At high frame rates, it is possible that frames are dropped in recorded MJPEG/AVI videos when selected storage (internal or removable) is accessed by other apps or the OS.
    • One of the best video players to view the recorded MJPEG/AVI videos is MX Player. For smoothest playback, make sure to enable hardware acceleration in Settings.
  9. Playing your recorded videos:
    • One of the best video players to view your videos recorded by your Mobius ActionCam or #16 camera is MX Player. For smoothest playback, make sure to enable hardware acceleration in Settings.

Android Buying Tips:

  1. Warning: Before buying a device running Android 4.3, please read carefully section Most Annoying Issues with Android 4.3 near the top of this page.
  2. If you are shopping for an Android device, as with many other types of products, you have the choice between brand name products and lower cost products.
  3. Many (but not all) lower cost products support Host USB and have a USB OTG adapter included. Although they may be financially attractive, they are not suitable for everyone. If you are technically proficient, they may well be a good choice; but if you are not, you might be better off going for brand name products.
  4. In any case, if you intent to run aMCA/ExtCam apps on your device, make sure it does support Host USB (as per new app app OTG Status); also make sure Google Play Store is installed and working.
  5. Most lower cost tablets are missing USB Authorizations even if they support Host USB. That problem can be fixed using Step 3 of these instructions. If you are technically proficient, it should not be a problem; otherwise it may well be mission impossible.
  6. The bottom line ? If you are technically proficient, you can probably afford to buy a lower cost product and invest a few hours to get it working right; if you are not, it may be wise to go for a brand name product.
