android - PackageManager 死亡 - DeadObjectException - 小包裹交易失败

Question

我有一个非常简单的函数，如下所示:

public static boolean isAppInstalled(String packageName) {
    PackageManager pm = MainApp.get().getPackageManager();
    try {
        pm.getPackageInfo(packageName, PackageManager.GET_ACTIVITIES);
        return true;
    } catch (PackageManager.NameNotFoundException e) {
        return false;
    }
}

有时这会在具有以下堆栈跟踪的 getPackageInfo 行崩溃:

java.lang.RuntimeException: Package manager has died
    at android.app.ApplicationPackageManager.getPackageInfo(ApplicationPackageManager.java:151)
    ... code in my app => getPackageInfo line above ...
Caused by: android.os.DeadObjectException: Transaction failed on small parcel; remote process probably died
    at android.os.BinderProxy.transactNative(Native Method)
    at android.os.BinderProxy.transact(Binder.java:505)
    at android.content.pm.IPackageManager$Stub$Proxy.getPackageInfo(IPackageManager.java:2151)
    at android.app.ApplicationPackageManager.getPackageInfo(ApplicationPackageManager.java:145)
    ...

知道为什么会发生这种情况吗？我认为只有在同时安装/卸载应用程序时才会发生这种情况，但我有一个用户可以重复此操作并始终遇到此异常。
