Is it possible to consistently detect if an Activity has hardware acceleration enabled when it is created? I\'m worried that users of my library will enable it through the m
I'm new in Android so I was stuck even with the clues given in the answer above.. went to search around and found this code somewhere in the sea of Google. Hope it helps someone.
/**
* Returns true if the given Activity has hardware acceleration enabled
* in its manifest, or in its foreground window.
*
* TODO(husky): Remove when initialize() is refactored (see TODO there)
* TODO(dtrainor) This is still used by other classes. Make sure to pull some version of this
* out before removing it.

public static boolean hasHardwareAcceleration(Activity activity) {
// Has HW acceleration been enabled manually in the current window?
Window window = activity.getWindow();
if (window != null) {
if ((window.getAttributes().flags
& WindowManager.LayoutParams.FLAG_HARDWARE_ACCELERATED) != 0) {
return true;
}
}
// Has HW acceleration been enabled in the manifest?
try {
ActivityInfo info = activity.getPackageManager().getActivityInfo(
activity.getComponentName(), 0);
if ((info.flags & ActivityInfo.FLAG_HARDWARE_ACCELERATED) != 0) {
return true;
}
} catch (PackageManager.NameNotFoundException e) {
Log.e("Chrome", "getActivityInfo(self) should not fail");
}
return false;
}
Try FLAG_HARDWARE_ACCELERATED
in flags
in ActivityInfo
for the activity, which you would get from PackageManager
via getActivityInfo()
.
