How to determine if an Activity exists on the current device

28 Dec 2011
android activity

This code snippet won’t work since startActivity dosen’t throw the exception ActivityNotFoundException:

try {
    startActivity(new Intent(...));
} catch (ActivityNotFoundException e) {
    Toast.makeText(this, "Not installed.", LENGTH_SHORT).show();

You maybe want to try this:

public boolean isCallable(Intent intent) {
    return getContext().getPackageManager().resolveActivity(
            intent, PackageManager.MATCH_DEFAULT_ONLY) != null;

    // or(I havn't try it):
    // List list = getPackageManager().queryIntentActivities(
    //         intent, PackageManager.MATCH_DEFAULT_ONLY);
    // return list.size() > 0;
