全局捕获异常

1.配置ndk

android {
    compileSdkVersion 28
    defaultConfig {
       ndk {
            // 设置支持的SO库架构
            abiFilters 'armeabi' //, 'x86', 'armeabi-v7a', 'x86_64', 'arm64-v8a'
        }
    }
}

2.添加依赖：

implementation 'com.tencent.bugly:crashreport:latest.release' //其中latest.release指代最新Bugly SDK版本号，也可以指定明确的版本号，例如2.1.9
implementation 'com.tencent.bugly:nativecrashreport:latest.release' //其中latest.release指代最新Bugly NDK版本号，也可以指定明确的版本号，例如3.0

3.导入CrashHandler类

public class CrashHandler implements Thread.UncaughtExceptionHandler {

    private static CrashHandler sInstance = null;
    private Thread.UncaughtExceptionHandler mDefaultHandler;
    private Context mContext;
    // 保存手机信息和异常信息
    private Map<String, String> mMessage = new HashMap<>();

    public static CrashHandler getInstance() {
        if (sInstance == null) {
            synchronized (CrashHandler.class) {
                if (sInstance == null) {
                    synchronized (CrashHandler.class) {
                        sInstance = new CrashHandler();
                    }
                }
            }
        }
        return sInstance;
    }

    private CrashHandler() {
    }

    /**
     * 初始化默认异常捕获
     *
     * @param context context
     */
    public void init(Context context) {
        mContext = context;
        // 获取默认异常处理器
        mDefaultHandler = Thread.getDefaultUncaughtExceptionHandler();
        // 将此类设为默认异常处理器
        Thread.setDefaultUncaughtExceptionHandler(this);
    }

    @Override
    public void uncaughtException(Thread t, Throwable e) {
        if (!handleException(e)) {
            // 未经过人为处理,则调用系统默认处理异常,弹出系统强制关闭的对话框
            if (mDefaultHandler != null) {
                mDefaultHandler.uncaughtException(t, e);
            }
        } else {
            // 已经人为处理,系统自己退出
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e1) {
                e1.printStackTrace();
            }
            System.exit(1);
        }
    }

    /**
     * 是否人为捕获异常
     *
     * @param e Throwable
     * @return true:已处理 false:未处理
     */
    private boolean handleException(Throwable e) {
        if (e == null) {// 异常是否为空
            return false;
        }
        new Thread() {// 在主线程中弹出提示
            @Override
            public void run() {
                Looper.prepare();
                Toast.makeText(mContext, "捕获到异常", Toast.LENGTH_SHORT).show();
                Looper.loop();
            }
        }.start();
        collectErrorMessages();
        saveErrorMessages(e);
        return false;
    }

    /**
     * 1.收集错误信息
     */
    private void collectErrorMessages() {
        PackageManager pm = mContext.getPackageManager();
        try {
            PackageInfo pi = pm.getPackageInfo(mContext.getPackageName(), PackageManager.GET_ACTIVITIES);
            if (pi != null) {
                String versionName = TextUtils.isEmpty(pi.versionName) ? "null" : pi.versionName;
                String versionCode = "" + pi.versionCode;
                mMessage.put("versionName", versionName);
                mMessage.put("versionCode", versionCode);
            }
            // 通过反射拿到错误信息
            Field[] fields = Build.class.getFields();
            if (fields != null && fields.length > 0) {
                for (Field field : fields) {
                    field.setAccessible(true);
                    try {
                        mMessage.put(field.getName(), field.get(null).toString());
                    } catch (IllegalAccessException e) {
                        e.printStackTrace();
                    }
                }
            }
        } catch (PackageManager.NameNotFoundException e) {
            e.printStackTrace();
        }
    }

    /**
     * 2.保存错误信息
     *
     * @param e Throwable
     */
    private void saveErrorMessages(Throwable e) {
        StringBuilder sb = new StringBuilder();
        for (Map.Entry<String, String> entry : mMessage.entrySet()) {
            String key = entry.getKey();
            String value = entry.getValue();
            sb.append(key).append("=").append(value).append("\n");
        }
        Writer writer = new StringWriter();
        PrintWriter pw = new PrintWriter(writer);
        e.printStackTrace(pw);
        pw.close();
        String result = writer.toString();
        sb.append(result);
       // String time = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss",Locale.CHINA).format(new Date());
        String fileName = "crash-"+System.currentTimeMillis()+"-"+".log";
        // 有无SD卡
        if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {
            String path = Environment.getExternalStorageDirectory().getPath()+"/crash/";
            File dir = new File(path);
            if (!dir.exists()) dir.mkdirs();
            FileOutputStream fos = null;
            try {
                fos = new FileOutputStream(path + fileName);
                fos.write(sb.toString().getBytes());
            } catch (Exception e1) {
                e1.printStackTrace();
            } finally {
                if (fos != null) {
                    try {
                        fos.close();
                    } catch (IOException e1) {
                        e1.printStackTrace();
                    }
                }
            }
        }
    }
}

4.在Application中配置

CrashHandler.getInstance().init(this);
CrashReport.initCrashReport(getApplicationContext(), "e5252aea86", false);
