PackageManager 的 applicationInfo.name 始终为 null [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 返回有效的包名称，但 applicationInfo.name 始终为 null.

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

推荐答案

使用applicationInfo.loadLabel(packageManagerInstance)来查找Application名称，但是applicationInfo.name应该是有原因的 没用.

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

编辑

applicationInfo.name 是 Application 子类的名称(如果有).

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