Android: App cannot play video in emulator

+1 vote
318 views

I have installed my custom app in Packages/apps/

in the app, I use a simple Videoview for video playbacks (3gp or mp4). it works in actual device/ADT emulator, but If I run it in AOSP emulator, it says "Failed to open file : the path of the video"

// Retrieving file from internal file 
systemVideo.setVideoURI(Uri.parse("android.resource://" + getPackageName() + "/" + R.drawable.test));

I found that most released apps(including system apps) can be debugged on the emulator by the way following:
1. install the app on the emulator, and launch it
2. run adb shell ps to get the pid of the app
3. run adb jdwp, if you find the pid in the output, then you can attach to the app by running
adb forward tcp:1234 jdwp:$pid_you_find and jdb -connect com.sun.jdi.SocketAttach:hostname=localhost,port=1234
4. you can use commands such as "classes" to see the classes of the app, even "stop" to set breakpoint and "eval" to run many functions and see the members of the objects.
I have 2 questions:
1. Why these tricks fail on the phones? What's the difference between the rom of emulator and phones?
2. How to avoid my app being debugged through such way?

I find that the emulator's memory increase rapidly when check GPU on. You can do the reproduction as following:
1. Turn on GPU following http://developer.android.com/tools/devices/emulator.html#acceleration
2. Power on the emulator
3. Launch some apps by mouse, (i,e. launch Settings then Clock, and Settings then Clock ...)
4. Check the memory usage of emulator by top command on Ubuntu and ProcessExplorer on Windows

I found that the apps with property android:hardwareAccelerated="true" is more worse.

I understand not allowing apps to automatically install home screen widgets as it could be annoying but for n00bish users it can be a challenge to instruct them on how to do so and so it DRASTICALLY weakens the business case for building a widget (and thereby diminishes a defining feature of Android).
To remedy this I wanted to suggest either an API that allows for installing a home screen widget after a confirmation with the user and/or an app permission that allows an app to install home screen widgets and/or a feature on Google Play that could take care of the confirming and installing.
