Android studio的错误记录
主要用来记录在做AS项目时候遇到的问题。
问题1：原本的工程是可以运行的，但是在使用databinding之后，就莫名出现下面的问题。
Error:(47, 5) 错误: 方法不会覆盖或实现超类型的方法
Error:(50, 24) 错误: 不兼容的类型: Context无法转换为Activity
在网上也没怎么收到解决方案：唯一找到的说是：JDK引入版本错误，重新更新版本就可以了（我觉得我的不是这个问题）。连接：http://www.myexception.cn/ruby-rails/1312454.html。
问题2:主要报错Caused by: org.xmlpull.v1.XmlPullParserException: Binary XML file line #3: <item> tag requires a 'drawable' attribute or child tag defining a drawable

问题3:一般来说这是因为环境路径没有配置好的原因，我这里只是因为没有更新项目版本
问题4:android.view.InflateException: Binary XML file line #79: Error inflating class <unknown>
这里其实已经把错误的位置告诉了我们，这里一般是xml中相关定义的错误。
问题5：在插件中可以运行，但是跑到宿主里面运行就报错：
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.liefengtech.tv.launcher/com.ryg.dynamicload.DLProxyFragmentActivity}: java.lang.RuntimeException: Parcelable encounteredClassNotFoundException reading a Serializable object (name = com.liefeng.plugin.restapi.vo.propertytvbox.AppHomeImageVo)
Caused by: java.lang.ClassNotFoundException: Didn't find class "com.liefeng.plugin.restapi.vo.propertytvbox.AppHomeImageVo" on path: DexPathList[[zip file "/data/app/com.liefengtech.tv.launcher-1.apk"],nativeLibraryDirectories=[/data/app-lib/com.liefengtech.tv.launcher-1, /system/lib]]
因为尝试了很多方法都没有成功，于是将传递的AppHomeImageVo分解成了简单的String类型来传递。
问题6：运行clean时报错：
Unable to delete file: E:\android\Project\lfxx-android-tv\lfxxapp\plugin2\build\intermediates\exploded-aar\com.android.support\animat
ed-vector-drawable\24.2.0\jars\classes.jar
查了一下，都说是权限的问题，这里我直接将文件下的jar包删除了。然后就没有报错。
问题7：关于使用viewpager内存溢出
这里主要在生成view的时候，出现内存溢出的情况。
报错代码：View introduceView6 = getLayoutInflater().inflate(R.layout.healthkl6, null);
这里生成了许多个view，当view数量比较少的时候没有问题，当view达到一定数量出现内存溢出的现象。此外，在运行在真机上时，会出现内存溢出，但是跑到虚拟机上不会 出现内存溢出，跑到宿主中也不会出现内存溢出。
