Android application捕获崩溃异常怎么办

Android application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

public class HKBaseApplication extends Application {
// activity对象列表,用于activity统一管理
private List<Activity> activityList;
// 异常捕获
protected boolean isNeedCaughtExeption = true;// 是否捕获未知异常
private PendingIntent restartIntent;
private MyUncaughtExceptionHandler uncaughtExceptionHandler;
private String packgeName;

@Override
public void onCreate() {
super.onCreate();

activityList = new ArrayList<Activity>();
packgeName = getPackageName();

if (isNeedCaughtExeption) {
 cauchException();
}
}

// -------------------异常捕获-----捕获异常后重启系统-----------------//

private void cauchException() {
Intent intent = new Intent();
// 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 = new MyUncaughtExceptionHandler();
Thread.setDefaultUncaughtExceptionHandler(uncaughtExceptionHandler);
}

// 创建服务用于捕获崩溃异常
private class MyUncaughtExceptionHandler implements UncaughtExceptionHandler {
@Override
public void uncaughtException(Thread thread, Throwable ex) {
 // 保存错误日志
 saveCatchInfo2File(ex);

// 1秒钟后重启应用
 AlarmManager mgr = (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
*/
private String saveCatchInfo2File(Throwable ex) {
Writer writer = new StringWriter();
PrintWriter printWriter = new PrintWriter(writer);
ex.printStackTrace(printWriter);
Throwable cause = ex.getCause();
while (cause != null) {
 cause.printStackTrace(printWriter);
 cause = cause.getCause();
}
printWriter.close();
String sb = writer.toString();
try {
 DateFormat formatter = new SimpleDateFormat("yyyy-MM-dd-HH-mm-ss");
 String time = formatter.format(new Date());
 String fileName = time + ".txt";
 System.out.println("fileName:" + fileName);
 if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {
 String filePath = Environment.getExternalStorageDirectory() + "/HKDownload/" + packgeName
  + "/crash/";
 File dir = new File(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);
 FileOutputStream fos = new FileOutputStream(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
 }
 return fileName;
} catch (Exception e) {
 System.out.println("an error occured while writing file..." + e.getMessage());
}
return null;
}

// ------------------------------activity管理-----------------------//

// activity管理：从列表中移除activity
public void removeActivity(Activity activity) {
activityList.remove(activity);
}

// activity管理：添加activity到列表
public void addActivity(Activity activity) {
activityList.add(activity);
}

// activity管理：结束所有activity
public void finishAllActivity() {
for (Activity activity : activityList) {
 if (null != activity) {
 activity.finish();
 }
}
}

// 结束线程,一般与finishAllActivity()一起使用
// 例如: finishAllActivity;finishProgram();
public void finishProgram() {
android.os.Process.killProcess(android.os.Process.myPid());
}
}
