An Android permission library extending Google's EasyPermissions with convenient additions.

Don't say very easy, say effortless. —— 128 Words to Use Instead of "Very"

Google Play

Sample APK

Why EffortlessPermissions?

  • Used as a drop-in replacement for Google's EasyPermissions and based on its battle-tested implementation.
  • Added an @AfterPermissionDenied annotation for methods to run automatically after denial.
  • Included consumer ProGuard rules missing in EasyPermissions which fixes your release build.
  • Added more method overloads which make coding easier.
  • Added another DialogFragment to open app detail settings which you have more control upon, e.g. dialog title can be hidden now.

In a word, just start with EffortlessPermissions instead of EasyPermissions.

Integration

Gradle:

compile 'me.zhanghai.android.effortlesspermissions:library:1.0.2'

Usage

Just use EffortlessPermission wherever you would use EasyPermissions (documentation), and explore the improvements listed above!

And here is a fully-working sample implementation, handling permission requesting both normally and after permanent denial:

public class MainActivity extends AppCompatActivity {

    private static final int REQUEST_CODE_SAVE_FILE_PERMISSION = 1;
    private static final String[] PERMISSIONS_SAVE_FILE = {
            Manifest.permission.WRITE_EXTERNAL_STORAGE
    };

    ...

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,
                                           @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);

        // Dispatch to our library.
        EffortlessPermissions.onRequestPermissionsResult(requestCode, permissions, grantResults,
                this);
    }

    // Call back to the same method so that we'll check and proceed.
    @AfterPermissionGranted(REQUEST_CODE_SAVE_FILE_PERMISSION)
    private void saveFile() {
        if (EffortlessPermissions.hasPermissions(this, PERMISSIONS_SAVE_FILE)) {
            // We've got the permission.
            saveFileWithPermission();
        } else if (EffortlessPermissions.somePermissionPermanentlyDenied(this,
                PERMISSIONS_SAVE_FILE)) {
            // Some permission is permanently denied so we cannot request them normally.
            OpenAppDetailsDialogFragment.show(
                    R.string.save_file_permission_permanently_denied_message,
                    R.string.open_settings, this);
        } else  {
            // Request the permissions.
            EffortlessPermissions.requestPermissions(this,
                    R.string.save_file_permission_request_message,
                    REQUEST_CODE_SAVE_FILE_PERMISSION, PERMISSIONS_SAVE_FILE);
        }
    }

    @AfterPermissionDenied(REQUEST_CODE_SAVE_FILE_PERMISSION)
    private void onSaveFilePermissionDenied() {
        // User denied at least some of the required permissions, report the error.
        Toast.makeText(this, R.string.save_file_permission_denied, Toast.LENGTH_SHORT).show();
    }

    private void saveFileWithPermission() {
        // It's show time!
        Toast.makeText(this, R.string.save_file_show_time, Toast.LENGTH_SHORT).show();
    }
}

Without EffortlessPermissions, you would have to make your activity implement PermissionCallbacks, check request code and call permission denied callback manually. You would also need to remember writing the ProGuard rules for every project or you'll end up debugging your release build to find it out. But now, only the truly necessary code is written. Cheers!

ProGuard

The AAR of this library has already included a consumer ProGuard file to retain the annotations and annotated methods.
