有没有办法仅在特定应用程序打开时执行服务(启动或停止)?情况是我有一个“泡泡”服务(类似于 facebook),我只想在我打开游戏 Minecraft PE 时出现。当我更改或打开另一个应用程序时,我想放置隐形气泡。这可能吗?

使用此代码。

public class CheckRunningApplicationReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context aContext, Intent anIntent) {
        try {            
            ActivityManager am = (ActivityManager) aContext
                    .getSystemService(Context.ACTIVITY_SERVICE);
            List<ActivityManager.RunningTaskInfo> alltasks = am
                    .getRunningTasks(1);
            for (ActivityManager.RunningTaskInfo aTask : alltasks) {

                if (aTask.topActivity.getClassName().equals("com.android.phone.InCallScreen")
                    || aTask.topActivity.getClassName().equals("com.android.contacts.DialtactsActivity"))
                {
                    Toast.makeText(aContext, "Phone Call Screen.", Toast.LENGTH_LONG).show();   
                }
                String packageName = "com.example.checkcurrentrunningapplication";

                if (aTask.topActivity.getClassName().equals(
                        packageName + ".Main"))
                {
                   // When opens this example screen then show a alert message
                   Toast.makeText(aContext, "Check Current Running Application Example Screen.", 
                                   Toast.LENGTH_LONG).show();   
                }
            }

        } catch (Throwable t) {
            Log.i("THROW", "Throwable caught: "
                        + t.getMessage(), t);
        }
    }
}

在清单中添加:

<receiver android:name = ".CheckRunningApplicationReceiver"/>
<uses-permission android:name="android.permission.GET_TASKS" />
