PackageManager的applicationInfo.name总是空 [英] PackageManager's applicationInfo.name is always null

问题描述

PackageManager pm = this.getPackageManager();
ActivityManager am = (ActivityManager) this.getSystemService(Context.ACTIVITY_SERVICE);

List<RunningAppProcessInfo> runningAppProcesses = am.getRunningAppProcesses();

for(RunningAppProcessInfo process : runningAppProcesses) {
    try {
        ApplicationInfo ai = pm.getApplicationInfo(process.processName, PackageManager.GET_META_DATA);
        Log.d(TAG, applicationInfo.name + "");
    } catch (NameNotFoundException e) {
        e.printStackTrace();
    }
}

process.processName 返回一个有效的软件包名称，但 applicationInfo.name 始终为空。

process.processName returns a valid package name but applicationInfo.name is always null.

推荐答案

用于 applicationInfo.loadLabel（packageManagerInstance）查找应用程序的名称，但应该有一个原因 applicationInfo.name 没有工作。

Used applicationInfo.loadLabel(packageManagerInstance) to find the Application name, but there should be a reason why applicationInfo.name didn't work.

修改

applicationInfo.name 是应用程序的名称的子类，如果您有任何。

applicationInfo.name is the name of a Application subclass if you have any.
