我每次尝试运行我的应用程序时都会收到此错误，我不知道为什么即时尝试为我的应用程序创建一个基本的欢迎屏幕，然后转换到我的主页，但目前欢迎屏幕没有加载和应用程序只是在运行项目时说“无法运行应用程序”。我已经尝试过对项目进行干净的构建和重建以及其他人已经拥有但仍然没有运气的其他修复。
下面我发布了logcat在运行时提供的错误。

以下是我的MainActivity代码：
package com.example.ross.moviepickerapp;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.app.AppCompatDelegate;
public class MainActivity extends AppCompatActivity
{
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
setContentView(R.layout.welcome_screen);
}
}
这是我的XMl代码：

你可能有问题
BindingContext。尝试对此行进行注释并清理项目并运行。
使用新的＆gt;创建新的Android活动空活动，看看它是如何运作的。
答案 1 :(得分：0)
Caused by: android.content.res.Resources$NotFoundException: Resource "com.example.ross.moviepickerapp:drawable/welcomebackground" (7f060064) is not a Drawable (color or path): TypedValue{t=0x1/d=0x7f060064 a=-1 r=0x7f060064}
您需要检查此文件。
您可以通过Android Studio添加资源，转到应用＆gt; res＆gt; drawable＆gt;“右键单击”＆gt;新＆gt;“图片资源”或“矢量资源”

我不知道它是否与带有compiledSdkVersion和targetSdkVersion的android库版本有关。以前我使用时出错：
然后我改为更新的版本，它起作用了：
我希望这会有所帮助
