本文介绍了一个关于APK间唤起导致闪退的问题及解决方案。问题出现在被唤起APK的LauncherActivity中，由于fragment管理不当引发错误。通过调整Intent的构造方式，直接指定目标组件，成功避免了问题。

使用apk A 唤起 apk B时使用PackageManager进行唤醒操作

        PackageManager packageManager = getPackageManager();
        Intent intent = packageManager.getLaunchIntentForPackage("com.xxx.xxx");

        if(intent != null) {
           startActivity(intent);
        }

apk B发生闪退，log显示

01-01 02:42:40.418  9356  9356 E AndroidRuntime: java.lang.IllegalStateException: Failure saving state: active fragment2{866132d (3063406e-5e0f-4ddc-9b3b-763c96d930c1) id=0x7f0a015d android:switcher:2131362141:1} was removed from the FragmentManager

经分析，原因在于apk B的Laucher Activity中fragment出现了某些问题导致的。通过报错信息一路跟踪发现起始操作在于onCreate方法的

super.onCreate(savedInstanceState);

一路跟踪至FragmentManagerImpl 2394行。猜测原因在于Intent调起apk时发生了一些问题。

最终通过换了一种调起apk方式解决问题

Intent intent = new Intent();
ComponentName componentName = new ComponentName("com.xxx.xxx", "com.xxx.xxx.xxx");
intent.setComponent(componentName);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
