Exception when opening Parse push notification [cl

问题:

I setup Parse push Android SDK 1.7.0 and can receive pushes without any problem. However, when opening the push notification my app crashes with the following exception:

android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat= flg=0x1000c000 (has extras) }

I also tried subclassing ParsePushBroadcastReceiver with getActivity() always returning the main activity class, same result. Below is the full stacktrace:

E/AndroidRuntime﹕ FATAL EXCEPTION: main
Process: com.ers.test, PID: 13513
java.lang.RuntimeException: Unable to start receiver com.ers.test.MyPushBroadcastReceiver: android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat= flg=0x1000c000 (has extras) }

After spending few hours. Found a solution: Implement your receiver and extends ParsePushBroadcastReceiver class.

Receiver.java

public class Receiver extends ParsePushBroadcastReceiver {

    @Override
    public void onPushOpen(Context context, Intent intent) {
        Log.e("Push", "Clicked");
        Intent i = new Intent(context, HomeActivity.class);
        i.putExtras(intent.getExtras());
        i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(i);
    }
}

Use it in manifest, (Instead of using ParsePushBroadcastReceiver)

Code for project's manifest:

<receiver
            android:name="your.package.name.Receiver"
            android:exported="false" >
            <intent-filter>
                <action android:name="com.parse.push.intent.RECEIVE" />
                <action android:name="com.parse.push.intent.DELETE" />
                <action android:name="com.parse.push.intent.OPEN" />
            </intent-filter>
        </receiver>

Happy Coding!!

The cause of this exception is when ParsePushBroadcastReceiver wants to open the empty uri in your push message in this code :

String uriString = null;
    try
    {
      JSONObject pushData = new JSONObject(intent.getStringExtra("com.parse.Data"));
      uriString = pushData.optString("uri");
    }
    catch (JSONException e)
    {
      Parse.logE("com.parse.ParsePushReceiver", "Unexpected JSONException when receiving push data: ", e);
    }
    if (uriString != null) {
          activityIntent = new Intent("android.intent.action.VIEW", Uri.parse(uriString));
        } else {
          activityIntent = new Intent(context, cls);
        }

If you just push a message, the uriString will be empty not null, So context.startActivity(activityIntent); will open an empty uri and exception occurs.

To solve this issue you can subclass ParsePushBroadcastReceiver (thanks to @Ahmad Raza) and override onPushopen like this :

public class Receiver extends ParsePushBroadcastReceiver {

    @Override
    protected void onPushOpen(Context context, Intent intent) {

        ParseAnalytics.trackAppOpenedInBackground(intent);

        String uriString = null;
        try {
            JSONObject pushData = new JSONObject(intent.getStringExtra("com.parse.Data"));
            uriString = pushData.optString("uri");
        } catch (JSONException e) {
            Log.v("com.parse.ParsePushReceiver", "Unexpected JSONException when receiving push data: ", e);
        }
        Class<? extends Activity> cls = getActivity(context, intent);
        Intent activityIntent;
        if (uriString != null && !uriString.isEmpty()) {
            activityIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(uriString));
        } else {
            activityIntent = new Intent(context, MainActivity.class);
        }
        activityIntent.putExtras(intent.getExtras());
        if (Build.VERSION.SDK_INT >= 16) {
            TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
            stackBuilder.addParentStack(cls);
            stackBuilder.addNextIntent(activityIntent);
            stackBuilder.startActivities();
        } else {
            activityIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            activityIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            context.startActivity(activityIntent);
        }
    }
} 

and update Manifest like this :

<receiver
            android:name="your.package.name.Receiver"
            android:exported="false" >
            <intent-filter>
                <action android:name="com.parse.push.intent.RECEIVE" />
                <action android:name="com.parse.push.intent.DELETE" />
                <action android:name="com.parse.push.intent.OPEN" />
            </intent-filter>
        </receiver>

I hope they solve the problem in their next update.
