我收到了很多用户报告,称我的应用程序崩溃。不断出现的错误似乎与我的parse.com初始化相关,但是,我已按照parse教程中的说明进行设置。
以下是堆栈跟踪:
java.lang.RuntimeException: Unable to start receiver com.parse.ParseBroadcastReceiver: java.lang.RuntimeException: applicationContext is null. You must call Parse.initialize(context, applicationId, clientKey) before using the Parse library.

这是我的初始化代码:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home_screen);
Parse.initialize(this, "hGG5RdgNVdI7eCeZynV32lWYXywQRHkpp5zLdY7Q", "TwmNbpBYEt4u3euE3lzNIgwyroSl8RPGF2dJFsPv");
ParseInstallation.getCurrentInstallation().saveInBackground();
请问有谁能看出导致这个错误的原因,并且知道如何修复吗?
以下是我的接收器代码:
public static class Receiver extends ParsePushBroadcastReceiver {
private String notificationText;
private Boolean notificationreceived = false;
public Receiver(){
}
private static final String TAG = "MyNotificationsReceiver";
@Override
public void onPushOpen(Context context, Intent intent) {
Log.e("Push", "Clicked");
Intent i = new Intent(context, HomeScreen.class);
notificationreceived = true;
i.putExtra("alert",notificationText);
i.putExtra("alertreceived", notificationreceived);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
Scb998.scb988b=true;
try {
JSONObject json = new JSONObject(intent.getExtras().getString("com.parse.Data"));
Scb998.msg = json.getString("alert");
} catch (JSONException e) {
Log.d(TAG, "JSONException: " + e.getMessage());
}
}
}
