如何停止或暂停Pandora和Spotify的 [英] How to stop or pause Pandora and Spotify
问题描述
我有一个应用程序有一个特点，推出一个应用程序，Pandora电台，或快捷方式。这一切工作正常。后来我想停止的应用程序，我开始。这适用于除Pandora和Spotify的大多数事情并不总是关闭。有时他们做，但并非总是如此。这似乎是与当前用户界面状态。例如，它工作正常，当我有潘多拉放映或主屏幕显示。当家庭Dock或租车模式有效时，它不能正常工作。你可以看到我所有的源$ C $ C在这里：的http：// code。 google.com/p/a2dpvolume/ service.java是具有这种功能的文件
I have an app that has a feature to launch an app, Pandora station, or shortcut. That all works fine. Later I want to stop the app I started. This works for most things except Pandora and Spotify don't always close. Sometimes they do but not always. It seems to be related to the current UI state. For instance, it works fine when I have Pandora showing or the home screen showing. When Home Dock or Car Mode is active it does not work. You can see all my source code here: http://code.google.com/p/a2dpvolume/ service.java is the file that has this functionality.
下面是该code，试图停止播放音乐，然后停止应用程序的部分。
Here is the part of that code that tries to stop the music from playing and then stop the app.
if (bt2.hasIntent()) {
// if music is playing, pause it
if (am2.isMusicActive()) {
// first pause the music so it removes the notify icon
Intent i = new Intent("com.android.music.musicservicecommand");
i.putExtra("command", "pause");
sendBroadcast(i);
// for more stubborn players, try this too...
Intent downIntent2 = new Intent(Intent.ACTION_MEDIA_BUTTON, null);
KeyEvent downEvent2 = new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MEDIA_STOP);
downIntent2.putExtra(Intent.EXTRA_KEY_EVENT, downEvent2);
sendOrderedBroadcast(downIntent2, null);
}
// if we opened a package for this device, try to close it now
if (bt2.getPname().length() > 3 && bt2.isAppkill()) {
// also open the home screen to make music app revert to
// background
Intent startMain = new Intent(Intent.ACTION_MAIN);
startMain.addCategory(Intent.CATEGORY_HOME);
startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(startMain);
// now we can kill the app is asked to
final String kpackage = bt2.getPname();
CountDownTimer killTimer = new CountDownTimer(6000, 3000) {
@Override
public void onFinish() {
try {
stopApp(kpackage);
} catch (Exception e) {
e.printStackTrace();
Log.e(LOG_TAG, "Error " + e.getMessage());
}
}
@Override
public void onTick(long arg0) {
if (am2.isMusicActive()) {
// for more stubborn players, try this too...
Intent downIntent2 = new Intent(Intent.ACTION_MEDIA_BUTTON, null);
KeyEvent downEvent2 = new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MEDIA_STOP);
downIntent2.putExtra(Intent.EXTRA_KEY_EVENT, downEvent2);
sendOrderedBroadcast(downIntent2, null);
}
try {
stopApp(kpackage);
} catch (Exception e) {
e.printStackTrace();
Log.e(LOG_TAG, "Error " + e.getMessage());
}
}
};
killTimer.start();
}
}
下面是函数stopApp（）。
Here is the function stopApp().
protected void stopApp(String packageName) {
Intent mIntent = getPackageManager().getLaunchIntentForPackage(
packageName);
if (mIntent != null) {
try {
ActivityManager act1 = (ActivityManager) this
.getSystemService(ACTIVITY_SERVICE);
// act1.restartPackage(packageName);
act1.killBackgroundProcesses(packageName);
List<ActivityManager.RunningAppProcessInfo> processes;
processes = act1.getRunningAppProcesses();
for (ActivityManager.RunningAppProcessInfo info : processes) {
for (int i = 0; i < info.pkgList.length; i++) {
if (info.pkgList[i].contains(packageName)) {
android.os.Process.killProcess(info.pid);
}
}
}
} catch (ActivityNotFoundException err) {
err.printStackTrace();
Toast t = Toast.makeText(getApplicationContext(),
R.string.app_not_found, Toast.LENGTH_SHORT);
if (notify)
t.show();
}
}
}
有其他人遇到这个问题？我怎样才能可靠地阻止启动程序？我需要先得到它的暂停，并把它的背景。这是我遇到的问题。它适用于大多数情况，但不是全部。有些情况下，Pandora和Spotify的将不会对关键事件作出响应被发送，他们只是不停地播放。这样可以使通知图标活跃，使得应用前景的活性，所以我不能阻止它。
Has someone else run into this problem? How can I reliably stop the launched app? I need to first get it to pause and put it in the background. That is the problem I am having. It works for most situations but not all. Some cases Pandora and Spotify will not respond to the key event being sent and they just keep playing. This keeps the notify icon active and makes the app a foreground activity so I can't stop it.
推荐答案
我终于想通了，潘多拉不暂停音乐，当它看到一个断开耳机。所以，我不得不发送断开意图让潘多拉将暂停。暂停后，它能够被推向背景和杀害。
I finally figured out that Pandora does pause music when it sees a headset disconnect. So, I just had to send that disconnect intent so Pandora would pause. Once paused, it was able to be pushed to background and killed.
//Try telling the system the headset just disconnected to stop other players
Intent j = new Intent("android.intent.action.HEADSET_PLUG");
j.putExtra("state", 0);
sendBroadcast(j);
