使用活动上下文和使用应用程序上下文发送广播之间有区别吗

另一个附带的问题是,如果上下文已经是应用程序上下文,我想是做上下文。getApplicationContext()只会返回自身,对吗?

如果没有区别,它可能只会传入接收器旁边的应用程序,

或者更好的是,它可以在

onReceive(Context context, Intent intent), 

然后做上下文。getApplicationContext在那里?

// inside the receiver it will the following with the context:   
mContext.bindService(new Intent(mContext, OtherService.class), mInitServiceConnection, Context.BIND_AUTO_CREATE);

mContext.unbindService(mInitServiceConnection);

Intent newStartIntent = new Intent(mContext, InitService.class);
mContext.startService(newStartIntent);

接收器类似于:

class LocalBroadcastReceiver extends BroadcastReceiver {

    private final Context mContext;

    public LocalBroadcastReceiver(@NonNull Context context) {
        mAppContext = context;
    }

    @Override
    public void onReceive(Context context, Intent intent) {

    // could it here use the context to get application context, like: 
            mContext = context.getApplicationContext()

            //then do something like:
            Intent newStartIntent = new Intent(mContext, InitService.class);
            mContext.startService(startMailAccountInitIntent);
    }
}
