最近，我意识到在从独立 SDK 管理器更新一些 SDK 工具后，我在使用 Android Studio 时遇到了很多(奇怪的)问题，例如无法在右侧的 Android 预览 Pane 中看到 ProgressBar。它给了我错误
Exception raised during rendering: Binary XML file line #-1: Error inflating class <unknown> (Details)
但是，它在我的手机上运行得很好，所以我忽略了它。最近，当我尝试使用 ADB 运行我的应用程序时，应用程序崩溃并出现 logcat 中的一些错误。它们如下:

我记得很清楚，我没有更改任何应用程序的主题。我的 SplashActivity.java 的一部分如下:
public class SplashActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState); // line 27
setContentView(R.layout.activity_splash); // line 28
}
// ...
}
还有我的MainActivity.java:
public class MainActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main); // line 70
// ...
}
// ...
}
下图显示了我安装的SDK:
有人知道为什么会发生这种情况吗？请随时在下面的评论中询问任何问题。谢谢!
最佳答案
我通过将 gradle 中的 buildToolsVersion 从 23.0.3 降级到 23.0.2 部分解决了我的问题。这解决了我的所有问题，除了 ProgressBar 问题。当我设法解决这个问题时，我会发布更新。
关于java - 更新一些 SDK 工具后 Android 给我很多错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/38814580/
