推荐答案

MediaStore.INTENT_ACTION_MUSIC_PLAYER是德$ P $从API 15 pcated新的code是：

MediaStore.INTENT_ACTION_MUSIC_PLAYER is deprecated from API 15 the new code is:

try {
    String pkgname = "com.sec.android.app.music";
    PackageManager pkgmanager = getPackageManager();
    Intent intent = pkgmanager.getLaunchIntentForPackage(pkgname);
    startActivity(intent);
} catch(Exception e) {
    // music player not found
}

只需添加您的按钮侦听此code，它会调用默认的音乐播放器。

Just add this code on your button listener and it will call the default music player.
