在lib_base中创建MyApplication
public class MyApplication extends Application {
/**
* 上下文
*/
private static MyApplication instance;
@Override
public void onCreate() {
super.onCreate();
instance = this;
initRouter(this);
}
public static Context getInstance() {
return instance;
}
private void initRouter(MyApplication mApplication) {
// 这两行必须写在init之前，否则这些配置在init过程中将无效
if (UIUtils.isApkInDebug(instance)) {
//打印日志
ARouter.openLog();
//开启调试模式(如果在InstantRun模式下运行，必须开启调试模式！
//线上版本需要关闭,否则有安全风险)
ARouter.openDebug();
}
// 尽可能早，推荐在Application中初始化
ARouter.init(mApplication);
}
} /**
* 判断当前应用是否是debug状态
*/
public static boolean isApkInDebug(Context context) {
try {
ApplicationInfo info = context.getApplicationInfo();
return (info.flags & ApplicationInfo.FLAG_DEBUGGABLE) != 0;
} catch (Exception e) {
return false;
}
}这里要注意：如果你在debug模式下进行调试代码，ARouter.openDebug();一定要调用，否则ARouter会出现无效情况。
