我正在从Android加载所有应用程序然后我在我的启动器中显示它们(图标+名称)。代码如下所示:
public class PhoneAppItem
{
String mPackageName = null;
String mActivityName = null;
String mName = null;
ActivityInfo mActivityInfo = null;
public PhoneAppItem(String packageName, String activityName)
{
mPackageName = packageName;
mActivityName = activityName;
}
public void loadInfo()
{
PackageManager pm = MainApp.get().getPackageManager();
try
{
// following line throws the exception!
mActivityInfo = pm.getActivityInfo(new ComponentName(mPackageName, mActivityName), 0);
// some other code...
}
catch (PackageManager.NameNotFoundException e)
{
L.e(e);
mName = mPackageName;
}
catch (NullPointerException e)
{
L.e(e);
mName = mPackageName;
}
}
}
检索所有PhoneAppItem
项目的包名称和活动名称,如下所示(对于android< 5,它与唯一尚未知道此问题的设备相关):
List<PhoneAppItem> apps = new ArrayList<>();
ActivityManager activityManager = (ActivityManager) MainApp.get().getSystemService(Context.ACTIVITY_SERVICE);
List<ActivityManager.RunningAppProcessInfo> processInfos = activityManager.getRunningAppProcesses();
for (ActivityManager.RunningAppProcessInfo processInfo : processInfos)
{
try
{
ApplicationInfo ai = pm.getApplicationInfo(processInfo.processName, 0);
if (!excludedPackages.contains(ai.packageName))
apps.add(new PhoneAppItem(ai.packageName, ai.className));
}
catch (PackageManager.NameNotFoundException e) {}
}
我现在有一个用户得到以下异常:
android.content.pm.PackageManager$NameNotFoundException: ComponentInfo{com.package.myapp/com.package.myapp.app.MainApp}
at android.app.ApplicationPackageManager.getActivityInfo(ApplicationPackageManager.java:262)
at com.package.myap.classes.PhoneAppItem.h(PhoneAppItem.java:70)
...
观察
问题
有谁知道为什么会发生这种情况?
答案 0 :(得分:1)
如果processInfo.processName
不起作用,请尝试另一种获取包的方法:
processInfo.pkgList[0]
