Install APK with adb : $ platform-tools/adb install out/target/product/ge... Error message in logcat: D/PackageParser( 60): Scanning package: /data/ap... The error was created by android.content.pm.PackageParser , which compares the android:minSdkVersion and android:targetSdkVersion attributes of the uses-sdk element of AndroidManifest.xml in the APK file against the SDK version of the device or emulator. The SDK version on the device has to be greater than that required by android:minSdkVersion . In my case, since I built the package with AOSP, the target emulator has to be AOSP also. This is the relavant section in AndroidManifest.xml : <uses-sdk android:minSdkVersion="AOSP" ... And the relevant section in android.content.pm.PackageParser : if (minCode != null) { if (!minCode.equals(...

When I used AssetManager to open an XML file in a ContentProvider : getContext().getAssets().openFd("demo.xml"); it failed with this exception: java.io.FileNotFoundException: This file can not b... It turned out that openFd only works for asset files that are not compressed. It works on media files such as .mp3 , .jpg , .wmv etc., which are not compressed during packaging. XML files are compressed by dedault, causing openFd to fail. An Android ticket was opened on this issue.
