1、重新UncaughtExceptionHandler

public class CrashHandler implements Thread.UncaughtExceptionHandler {public static final String TAG = "CrashHandler";//系統(tǒng)默認(rèn)的UncaughtException處理類private Thread.UncaughtExceptionHandler mDefaultHandler;//CrashHandler實(shí)例private static CrashHandler instance;//程序的Context對(duì)象private Context mContext;//用來存儲(chǔ)設(shè)備信息和異常信息private Map<String, String> infos = new HashMap<String, String>();//用于格式化日期,作為日志文件名的一部分private DateFormat formatter = new SimpleDateFormat("yyyy-MM-dd-HH-mm-ss");/** 保證只有一個(gè)CrashHandler實(shí)例 */private CrashHandler() {}/** 獲取CrashHandler實(shí)例 ,單例模式 */public static CrashHandler getInstance() {if(instance == null)instance = new CrashHandler();return instance;}/*** 初始化*/public void init(Context context) {mContext = context;//獲取系統(tǒng)默認(rèn)的UncaughtException處理器mDefaultHandler = Thread.getDefaultUncaughtExceptionHandler();//設(shè)置該CrashHandler為程序的默認(rèn)處理器Thread.setDefaultUncaughtExceptionHandler(this);}/*** 當(dāng)UncaughtException發(fā)生時(shí)會(huì)轉(zhuǎn)入該函數(shù)來處理*/@Overridepublic void uncaughtException(Thread thread, Throwable ex) {if (!handleException(ex) && mDefaultHandler != null) {//如果用戶沒有處理則讓系統(tǒng)默認(rèn)的異常處理器來處理mDefaultHandler.uncaughtException(thread, ex);} else { // try { // Thread.sleep(3000); // } catch (InterruptedException e) { // Log.e(TAG, "error : ", e); // }//退出程序android.os.Process.killProcess(android.os.Process.myPid());System.exit(1);}}/*** 自定義錯(cuò)誤處理,收集錯(cuò)誤信息 發(fā)送錯(cuò)誤報(bào)告等操作均在此完成.** @param ex* @return true:如果處理了該異常信息;否則返回false.*/private boolean handleException(Throwable ex) {if (ex == null) {return false;}//收集設(shè)備參數(shù)信息collectDeviceInfo(mContext); // MyShareUtil.sharedPstring("updata","2"); // Intent intent = new Intent(mContext, MainActivity.class); // mContext.startActivity(intent);//使用Toast來顯示異常信息new Thread() {@Overridepublic void run() {Looper.prepare();Toast.makeText(mContext, "很抱歉,程序出現(xiàn)異常,即將退出", Toast.LENGTH_SHORT).show(); // ToastUtil.showError(mContext, "很抱歉,程序出現(xiàn)異常,即將退出.", Toast.LENGTH_SHORT);Looper.loop();}}.start();//保存日志文件saveCatchInfo2File(ex);return true;}/*** 收集設(shè)備參數(shù)信息* @param ctx*/public void collectDeviceInfo(Context ctx) {try {PackageManager pm = ctx.getPackageManager();PackageInfo pi = pm.getPackageInfo(ctx.getPackageName(), PackageManager.GET_ACTIVITIES);if (pi != null) {String versionName = pi.versionName == null ?

2、在Application類啟動(dòng)自定義類即可

CrashHandler catchHandler = CrashHandler.getInstance(); catchHandler.init(getApplicationContext());
