本篇内容主要讲解"Android中如何处理后台崩溃",感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷,实用性强。下面就让小编来带大家学习"Android中如何处理后台崩溃"吧!
原理其实蛮简单的。
检测是否为后台
如果是后台则杀掉该进程,否则执行默认的崩溃处理
检测是否为后台,这里我们以进程中Activity的数量作为判断标准
当activity onStart时activityCount自增
当Activity onStop时activityCount自减
当activityCount为0,我们则认为应用处于后台状态
具体实现如下:
object ActivityLifecycleCallbackImp: Application.ActivityLifecycleCallbacks { var activityCount: Int = 0 override fun onActivityPaused(activity: Activity?) { } override fun onActivityResumed(activity: Activity?) { } override fun onActivityStarted(activity: Activity?) { activityCount ++ } override fun onActivityDestroyed(activity: Activity?) { } override fun onActivitySaveInstanceState(activity: Activity?, outState: Bundle?) { } override fun onActivityStopped(activity: Activity?) { activityCount-- } override fun onActivityCreated(activity: Activity?, savedInstanceState: Bundle?) { } }
在Application中进行注册:
class MyApplication : Application() { override fun onCreate() { super.onCreate() registerActivityLifecycleCallbacks(ActivityLifecycleCallbackImp) } }
剩下的就是设置一个自定义的未捕获异常处理处理器:
val defaultHandler = Thread.getDefaultUncaughtExceptionHandler() Thread.setDefaultUncaughtExceptionHandler { thread, exception -> exception.printStackTrace() val isBackground = ActivityLifecycleCallbackImp.activityCount == 0 if (isBackground) { Log.d("MyApplication", "isBackground just kill the process without annoying users") android.os.Process.killProcess(android.os.Process.myPid()) } else { defaultHandler.uncaughtException(thread, exception) } }到此,相信大家对"Android中如何处理后台崩溃"有了更深的了解,不妨来实际操作一番吧!这里是网站,更多相关内容可以进入相关频道进行查询,关注我们,继续学习!
