PackageManager的applicationInfo.name始终为null
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。
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 returns a valid package name but applicationInfo.name is always null.

使用
applicationInfo.loadLabel(packageManagerInstance)查找应用程序名称，但applicationInfo.name不起作用应该是有原因的。Edit
applicationInfo.name是Application子类的名称（如果有的话）。Used
applicationInfo.loadLabel(packageManagerInstance)to find the Application name, but there should be a reason whyapplicationInfo.namedidn't work.Edit
applicationInfo.nameis the name of aApplicationsubclass if you have any.名称为 null 的原因是它确实是... null。
请参考Android清单文档：
您想要的是应用程序的名称，该名称在应用程序标签的 label 属性中设置，Ragunath 解释了如何获取该名称。
The reason name is null is that it really is... null.
Please refer to the Android manifest documentation:
What you want is the name of the application, which is set in the label attribute of the application tag, and which Ragunath explained how to get.
