Android application捕获崩溃异常怎么办
Androidapplication捕获崩溃异常怎么办？
通用application
1、收集所有avtivity用于彻底退出应用
2、捕获崩溃异常,保存错误日志,并重启应用
publicclassHKBaseApplicationextendsApplication{
//activity对象列表,用于activity统一管理
privateListactivityList;
//异常捕获
protectedbooleanisNeedCaughtExeption=true;//是否捕获未知异常
privatePendingIntentrestartIntent;
privateMyUncaughtExceptionHandleruncaughtExceptionHandler;
privateStringpackgeName;
@Override
publicvoidonCreate(){
super.onCreate();
activityList=newArrayList();
packgeName=getPackageName();
if(isNeedCaughtExeption){
cauchException();
}
}
//-------------------异常捕获-----捕获异常后重启系统-----------------//
privatevoidcauchException(){
Intentintent=newIntent();
//参数1：包名，参数2：程序入口的activity
intent.setClassName(packgeName,packgeName+".LoginActivity");
restartIntent=PendingIntent.getActivity(getApplicationContext(),-1,intent,
Intent.FLAG_ACTIVITY_NEW_TASK);
//程序崩溃时触发线程
uncaughtExceptionHandler=newMyUncaughtExceptionHandler();
Thread.setDefaultUncaughtExceptionHandler(uncaughtExceptionHandler);
}
//创建服务用于捕获崩溃异常
privateclassMyUncaughtExceptionHandlerimplementsUncaughtExceptionHandler{
@Override
publicvoiduncaughtException(Threadthread,Throwableex){
//保存错误日志
saveCatchInfo2File(ex);
//1秒钟后重启应用
AlarmManagermgr=(AlarmManager)getSystemService(Context.ALARM_SERVICE);
mgr.set(AlarmManager.RTC,System.currentTimeMillis()+1000,restartIntent);
//关闭当前应用
finishAllActivity();
finishProgram();
}
};
/**
*保存错误信息到文件中
*
*@return返回文件名称
*/
privateStringsaveCatchInfo2File(Throwableex){
Writerwriter=newStringWriter();
PrintWriterprintWriter=newPrintWriter(writer);
ex.printStackTrace(printWriter);
Throwablecause=ex.getCause();
while(cause!=null){
cause.printStackTrace(printWriter);
cause=cause.getCause();
}
printWriter.close();
Stringsb=writer.toString();
try{
DateFormatformatter=newSimpleDateFormat("yyyy-MM-dd-HH-mm-ss");
Stringtime=formatter.format(newDate());
StringfileName=time+".txt";
System.out.println("fileName:"+fileName);
if(Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)){
StringfilePath=Environment.getExternalStorageDirectory()+"/HKDownload/"+packgeName
+"/crash/";
Filedir=newFile(filePath);
if(!dir.exists()){
if(!dir.mkdirs()){
//创建目录失败:一般是因为SD卡被拔出了
return"";
}
}
System.out.println("filePath+fileName:"+filePath+fileName);
FileOutputStreamfos=newFileOutputStream(filePath+fileName);
fos.write(sb.getBytes());
fos.close();
//文件保存完了之后,在应用下次启动的时候去检查错误日志,发现新的错误日志,就发送给开发者
}
returnfileName;
}catch(Exceptione){
System.out.println("anerroroccuredwhilewritingfile..."+e.getMessage());
}
returnnull;
}
//------------------------------activity管理-----------------------//
//activity管理：从列表中移除activity
publicvoidremoveActivity(Activityactivity){
activityList.remove(activity);
}
//activity管理：添加activity到列表
publicvoidaddActivity(Activityactivity){
activityList.add(activity);
}
//activity管理：结束所有activity
publicvoidfinishAllActivity(){
for(Activityactivity:activityList){
if(null!=activity){
activity.finish();
}
}
}
//结束线程,一般与finishAllActivity()一起使用
//例如:finishAllActivity;finishProgram();
publicvoidfinishProgram(){
android.os.Process.killProcess(android.os.Process.myPid());
}
}
