在我的情况下,应用程序调用服务,服务将启动活动。我的问题是获取调用该服务的应用程序包。
有人可以帮我解决这个问题吗?

我是直接从android源码发现的,它运行正常:)
final ActivityManager am = (ActivityManager)
getSystemService(Context.ACTIVITY_SERVICE);
final List<ActivityManager.RecentTaskInfo> recentTasks =
am.getRecentTasks(3, ActivityManager.RECENT_IGNORE_UNAVAILABLE);
for (int i = 0, index = 0; i < 3 && (index < 3); ++i) {
final ActivityManager.RecentTaskInfo recentInfo = recentTasks.get(i);
Intent intent = new Intent( recentInfo.baseIntent);
if ( recentInfo.origActivity != null) {
intent.setComponent( recentInfo.origActivity);
}
final PackageManager pm = getPackageManager();
final ResolveInfo resolveInfo = pm.resolveActivity(intent, 0);
final ActivityInfo info = resolveInfo.activityInfo;
final String title = info.loadLabel(pm).toString();
Log.d("hello"," "+title+" "+info.packageName);
final ImageView iv = (ImageView)findViewById(R.id.imageView1);
iv.setImageDrawable(info.loadIcon(pm));
++index;
}

试试这个
ActivityManager am = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
List<RunningTaskInfo> tasks = am.getRunningTasks(1);
if (!tasks.isEmpty()) {
ComponentName topActivity = tasks.get(1).topActivity;
if (!topActivity.getPackageName().equals(context.getPackageName())) {
return true;
}
}
获得第二项顶级活动对您有用。
