I'm trying to run a sub process on Android (see this question) which requires that the PYTHONHOME environment variable be set. I tried to do so with the following code:
ProcessBuilder pbuilder = new ProcessBuilder("python/bin/python", "test.py");
pbuilder.directory(getFilesDir());
Map<String, String> env = pbuilder.environment();
env.put("PYTHONHOME", "python");
Process process = pbuilder.start();
but I get this exception:
E/AndroidRuntime(25857): FATAL EXCEPTION: main

Does anyone have any advice? I've tried wrapping the call to python in a shell script which exports PYTHONHOME but that didn't do the trick.

Just recently ran into the same problem. Seems like you can't modify the ProcessBuilder's environment map on Android versions <= 2.2. The only workaround that I found was to use exec() rather than the ProcessBuilder. In your case, this would result in something along the lines of:
String[] cmdarray = {"python/bin/python", "test.py"};
String[] envp = {"PYTHONHOME=python"};
Process process = Runtime.getRuntime().exec(cmdarray, envp, getFilesDir());
Hope that helps.

DownloadManager was added on API level 9 (aka Gingerbread).
My guess you declared minSDK as lower than 9 in your AndroidManifest.xml
If that is the case, you need to devise a workaround for users using older Android version.
You can check on which version your app is running by using the following code:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.GINGERBREAD) {
// Use DownloadManager
}
else {
// Workaround
}
i'm getting this message when i run my application i don't know why i'm getting it could any one help me. here is the logcat.

This happens when the build library classes conflict with those at run-time. Try performing a Clean of your project followed by a build.
I made an android project on Motodev (which is an eclipse plugin itself). But now when I am trying to run the same project on eclipse, the emulator gives me an error the following error:

That can be the result when you have compiled against a different library than you are using at runtime.
A good explanation can be had here.
Another possibility is having a duplicate class in the classpath somewhere, such as in a library jar.
Updated to the latest version of AdWhirl and AdMob SDK but getting a known error from the AdMob SDK in Android 2.1-update1. Found in this thread https://groups.google.com/forum/#!topic/google-admob-ads-sdk/cNxRgIUHJH0
but it refers to only and AdMob fix not AdWhirl any clue what changes can be made to the AdWhirl SDK to fix this?
Thanks In Advance!

The issue is not in the AdWhirl code, or even the AdMob code. This is a NullPointerException in the Android WebView, and there is no known workaround for the AdMob/AdWhirl code. This shouldn't be happening that often, but if it really is a deal breaker, you may want to turn down the number of requests you're sending to AdMob.
Yes, I also have this problem.
My workaround: extend AdWhirlLayout, override dispatchWindowFocusChanged and every other method that have this exception occurring and catch the exception.
There is an error in my Android application that happens quite often, based on the crash report on the Developer Console.

Unfortunately, I can't replicate that error on my Android phone.
I dont' know where to start: in the trace there isn't any reference to my code.
Can somebody give me some suggestions on how to identify the root of the problem, please?
Thanks,
Dan
The most obvious things I can think of:
AbsListView.obtainView() I believe is communicating with the Adopter to populate the list view. Make sure there is never a case where you could return a null back to the list view.
There may be a bug in some version of the platform. Unfortunately the developer console does not currently show you the platform version the error reports came from. Hopefully this will be added in the future to help diagnose such a situation.
It is possible someone is running a non-standard or custom build of the platform that has bugs. You might be able to determine this by looking at the "platforms" section for the different devices the error is coming from.
I would try creating a virtual device and load it in the emulator, start with the smallest resolution.
I am suspecting that it has to do with screen size and somehow you are trying to draw in a pixel that doesn't exist.
