收集Crash信息

通过Thread.UncaughtExceptionHandler来收集bug。

public class CrashHandler implements Thread.UncaughtExceptionHandler {    private static final String TAG = CrashHandler.class.getSimpleName();    private static final boolean DEBUG = true;    private static final String PATH = Environment.getExternalStorageDirectory().getPath() + "/CrashTest/log/";    private static final String FILE_NAME = "crash";    private static final String FILE_NAME_SUFFIX = ".trace";    private static CrashHandler sInstance = new CrashHandler();    private Thread.UncaughtExceptionHandler mDefaultCrashHandler;    private Context mContext;    public static CrashHandler getInstace() {        return sInstance;    }    private void init(Context context) {        mContext = context.getApplicationContext();        mDefaultCrashHandler = Thread.getDefaultUncaughtExceptionHandler();        Thread.setDefaultUncaughtExceptionHandler(this);    }    @Override    public void uncaughtException(Thread thread, Throwable ex) {        try {            //导出异常信息到SD卡            dumpExceptionToSDCard(ex);            //TODO 传到服务器        } catch (IOException e) {            e.printStackTrace();        }        ex.printStackTrace();        if (mDefaultCrashHandler != null) {            mDefaultCrashHandler.uncaughtException(thread, ex);        } else {            android.os.Process.killProcess(Process.myPid());        }    }    private void dumpExceptionToSDCard(Throwable ex) throws IOException {        if (!Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {            if (DEBUG) {                Log.w(TAG, "请检查内存卡");                return;            }        }        File dir = new File(PATH);        if (!dir.exists()) {            dir.mkdirs();        }        long current = System.currentTimeMillis();        @SuppressLint("SimpleDateFormat")        String time = new SimpleDateFormat("yyyy-MM-dd HH-mm-ss").format(new Date(current));        File file = new File(PATH + FILE_NAME + time + FILE_NAME_SUFFIX);        PrintWriter pw = null;        try {            pw = new PrintWriter(new BufferedWriter(new FileWriter(file)));            pw.println(time);            dumpPhoneInfo(pw);            pw.println();            ex.printStackTrace(pw);        } catch (Exception e) {            Log.e(TAG, "转存Crash信息失败！");        } finally {            if (pw != null) {                pw.close();            }        }    }    private void dumpPhoneInfo(PrintWriter pw) throws PackageManager.NameNotFoundException {        PackageManager pm = mContext.getPackageManager();        PackageInfo packageInfo = pm.getPackageInfo(mContext.getPackageName(), PackageManager.GET_ACTIVITIES);        //app版本号        pw.print("App Version: ");        pw.print(packageInfo.versionName);        pw.print("_");        pw.println(packageInfo.versionCode);        //系统版本号        pw.print("OS Version: ");        pw.print(Build.VERSION.RELEASE);        pw.print("_");        pw.println(Build.VERSION.SDK_INT);        //手机厂商        pw.print("vendor: ");        pw.println(Build.MANUFACTURER);        //手机型号        pw.print("Model: ");        pw.println(Build.MODEL);        //CPU架构        pw.print("CPU ABI: ");        pw.println(Build.CPU_ABI);    }}
