遇到了一個神坑，坑了一天 ，特此記錄下

遇到這個坑 各種Google:java.lang.RuntimeException: Unable to instantiate application 

網上各種說法都有，各種嘗試都測試了  其中一種解釋有些道理 就是說項目 分包錯誤 應該使用multidex，但是項目中也確實使用了multidex，全部都配置好了，而且還升級到了最新版本    感覺懷疑人生了。

既然網上的方法不行，就從自身代碼找問題，仔細排查代碼，發現切換到老版本可以，新的版本不行，那就逐漸縮小排查範圍，最後竟然發現是一個自定義註解的問題，之前發現一個自定義註解存在崩潰的情況，於是乎加了一個Try catch,正是這個小小的Try Catch 造成整個項目組delay了一天  

之前Work 的情況：

package chat.yee.android.mvp.widget.annotation;

import android.view.View;

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.aspectj.lang.reflect.MethodSignature;

import java.lang.reflect.Method;

@Aspect
public class SingleClickAspect {
    private static final long DEFAULT_TIME_INTERVAL = 5000;

    /**
     * 定義切點，標記切點爲所有被@SingleClick註解的方法
     * 注意：這裏me.baron.test.annotation.SingleClick需要替換成
     * 你自己項目中SingleClick這個類的全路徑哦
     */
    @Pointcut("execution(@chat.yee.android.mvp.widget.annotation.SingleClick * *(..))")
    public void methodAnnotated() {}

    /**
     * 定義一個切面方法，包裹切點方法
     */
    @Around("methodAnnotated()")
    public void aroundJoinPoint(ProceedingJoinPoint joinPoint) throws Throwable {
        // 取出方法的參數
        View view = null;
        for (Object arg : joinPoint.getArgs()) {
            if (arg instanceof View) {
                view = (View) arg;
                break;
            }
        }
        if (view == null) {
            return;
        }
        // 取出方法的註解
        MethodSignature methodSignature = (MethodSignature) joinPoint.getSignature();
        Method method = methodSignature.getMethod();
        if (!method.isAnnotationPresent(SingleClick.class)) {
            return;
        }
        SingleClick singleClick = method.getAnnotation(SingleClick.class);
        // 判斷是否快速點擊
        if (!XClickUtil.isFastDoubleClick(view, singleClick.value())) {
            // 不是快速點擊，執行原方法
            joinPoint.proceed();
        }
    }
}

 

出問題後的代碼：

package chat.yee.android.mvp.widget.annotation;

import android.view.View;

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.aspectj.lang.reflect.MethodSignature;

import java.lang.reflect.Method;

@Aspect
public class SingleClickAspect {
    private static final long DEFAULT_TIME_INTERVAL = 5000;

    /**
     * 定義切點，標記切點爲所有被@SingleClick註解的方法
     * 你自己項目中SingleClick這個類的全路徑哦
     */
    @Pointcut("execution(@chat.yee.android.mvp.widget.annotation.SingleClick * *(..))")
    public void methodAnnotated() {}

    /**
     * 定義一個切面方法，包裹切點方法
     */
    @Around("methodAnnotated()")
    public void aroundJoinPoint(ProceedingJoinPoint joinPoint) throws Throwable {
        // 取出方法的參數
        try {
            View view = null;
            for (Object arg : joinPoint.getArgs()) {
                if (arg instanceof View) {
                    view = (View) arg;
                    break;
                }
            }
            if (view == null) {
                return;
            }
            // 取出方法的註解
            MethodSignature methodSignature = (MethodSignature) joinPoint.getSignature();
            Method method = methodSignature.getMethod();
            if (method == null) {
                return;
            }
            if (!method.isAnnotationPresent(SingleClick.class)) {
                return;
            }
            SingleClick singleClick = method.getAnnotation(SingleClick.class);
            // 判斷是否快速點擊
            if (!XClickUtil.isFastDoubleClick(view, singleClick.value())) {
                // 不是快速點擊，執行原方法
                joinPoint.proceed();
            }
        } catch (Throwable throwable) {
            throwable.printStackTrace();
        }
    }
}

一個Try Catch 引發的翻車😭
