App全局异常捕获

App异常全局捕获，防止应用crash掉（不防ANR）。

/** * 异常捕获 * */
public class NeverCrash {
    

    private CrashHandler mCrashHandler;

    private static NeverCrash mInstance;

    private NeverCrash(){
    

    }

    private static NeverCrash getInstance(){
    
        if(mInstance == null){
    
            synchronized (NeverCrash.class){
    
                if(mInstance == null){
    
                    mInstance = new NeverCrash();
                }
            }
        }

        return mInstance;
    }

    public static void init(CrashHandler crashHandler){
    
        getInstance().setCrashHandler(crashHandler);
    }

    private void setCrashHandler(CrashHandler crashHandler){
    

        mCrashHandler = crashHandler;
        new Handler(Looper.getMainLooper()).post(new Runnable() {
    
            @Override
            public void run() {
    
                for (;;) {
    
                    try {
    
                        Looper.loop();
                    } catch (Throwable e) {
    
                        if (mCrashHandler != null) {
    //捕获异常处理
                            mCrashHandler.uncaughtException(Looper.getMainLooper().getThread(), e);
                        }
                    }
                }
            }
        });

        Thread.setDefaultUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler() {
    
            @Override
            public void uncaughtException(Thread t, Throwable e) {
    
                if(mCrashHandler!=null){
    //捕获异常处理
                    mCrashHandler.uncaughtException(t,e);
                }
            }
        });

    }

    public interface CrashHandler{
    
        void uncaughtException(Thread t,Throwable e);
    }
}

在application中使用：

NeverCrash.init {
     t, e ->
            Log.d(TAG, Log.getStackTraceString(e))
        }
