昨天我将我的Android工作室从2.2.3升级到2.3 然后得到一个错误
错误：SDK Build Tools修订版（24.0.2）对于项目'：app'来说太低了。最低要求是25.0.0“
当我尝试构建我的项目时。
所以，我将项目gradle文件更改为
compileSdkVersion 25
buildToolsVersion "25.0.0"
targetSdkVersion 25
compile 'com.android.support:appcompat-v7:25.0.1'
似乎一切正常，我已经成功运行了我的APP 但是当我点按手机上的按钮时 APP崩溃了。
另外，我引用了这篇文章java.lang.NoSuchMethodError: No static method isCtrlPressed(Landroid/view/KeyEvent;)

答案 0 :(得分：0)
当子类化AppCompatActivity时，在点击硬件后退按钮时会导致OP问题。解决方法是将Activity类子类化。
