遇到了一个神坑，坑了一天 ，特此记录下
遇到这个坑 各种Google:java.lang.RuntimeException: Unable to instantiate application
网上各种说法都有，各种尝试都测试了 其中一种解释有些道理 就是说项目 分包错误 应该使用multidex，但是项目中也确实使用了multidex，全部都配置好了，而且还升级到了最新版本 感觉怀疑人生了。
既然网上的方法不行，就从自身代码找问题，仔细排查代码，发现切换到老版本可以，新的版本不行，那就逐渐缩小排查范围，最后竟然发现是一个自定义注解的问题，之前发现一个自定义注解存在崩溃的情况，于是乎加了一个Try catch,正是这个小小的Try Catch 造成整个项目组delay了一天
之前Work 的情况：
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;
/**
* 定义切点，标记切点为所有被@SingleClick注解的方法
* 注意：这里me.baron.test.annotation.SingleClick需要替换成
* 你自己项目中SingleClick这个类的全路径哦
*/
@Pointcut("execution(@chat.yee.android.mvp.widget.annotation.SingleClick * *(..))")
public void methodAnnotated() {}
/**
* 定义一个切面方法，包裹切点方法
*/
@Around("methodAnnotated()")
public void aroundJoinPoint(ProceedingJoinPoint joinPoint) throws Throwable {
// 取出方法的参数
View view = null;
for (Object arg : joinPoint.getArgs()) {
if (arg instanceof View) {
view = (View) arg;
break;
}
}
if (view == null) {
return;
}
// 取出方法的注解
MethodSignature methodSignature = (MethodSignature) joinPoint.getSignature();
Method method = methodSignature.getMethod();
if (!method.isAnnotationPresent(SingleClick.class)) {
return;
}
SingleClick singleClick = method.getAnnotation(SingleClick.class);
// 判断是否快速点击
if (!XClickUtil.isFastDoubleClick(view, singleClick.value())) {
// 不是快速点击，执行原方法
joinPoint.proceed();
}
}
}
出问题后的代码：
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;
/**
* 定义切点，标记切点为所有被@SingleClick注解的方法
* 你自己项目中SingleClick这个类的全路径哦
*/
@Pointcut("execution(@chat.yee.android.mvp.widget.annotation.SingleClick * *(..))")
public void methodAnnotated() {}
/**
* 定义一个切面方法，包裹切点方法
*/
@Around("methodAnnotated()")
public void aroundJoinPoint(ProceedingJoinPoint joinPoint) throws Throwable {
// 取出方法的参数
try {
View view = null;
for (Object arg : joinPoint.getArgs()) {
if (arg instanceof View) {
view = (View) arg;
break;
}
}
if (view == null) {
return;
}
// 取出方法的注解
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);
// 判断是否快速点击
if (!XClickUtil.isFastDoubleClick(view, singleClick.value())) {
// 不是快速点击，执行原方法
joinPoint.proceed();
}
} catch (Throwable throwable) {
throwable.printStackTrace();
}
}
}
一个Try Catch 引发的翻车????
