我在Nexus 5仿真器（API 24 / Google API）上尝试运行我的代码（下面）时遇到上述异常......

我看到类似问题的答案，建议将SplashActivity.this传递给Dialog构造函数而不是传递getApplicationContext() - 但我已经传递了一个活动实例。
任何想法可能出错？
我的代码！...
private boolean checkPlayServices() {
GoogleApiAvailability googleAPI = GoogleApiAvailability.getInstance();
int result = googleAPI.isGooglePlayServicesAvailable(this);
if (result != ConnectionResult.SUCCESS) {
if (googleAPI.isUserResolvableError(result)) {
Dialog dialog = googleAPI.getErrorDialog(this, result, PLAY_SERVICES_RESOLUTION_REQUEST);
dialog.setOnCancelListener(new DialogInterface.OnCancelListener() {
@Override
public void onCancel(DialogInterface dialogInterface) {
SplashActivity.this.finish();
}
});
dialog.show();
}
return false;
}
return true;
}

下面的错误方式告诉你
java.lang.UnsupportedOperationException:
Failed to resolve attribute at index 6: TypedValue{t=0x2/d=0x101009b a=1}
这似乎是在尝试在目标设备上评估ColorStateList时发生的。因此，如果有任何XML属性与应用程序的minSdk不一致，我会检查颜色定义。通常，执行Lint也可能直接指向这样的错误，因为这非常适合查找这些内容（在命令行上使用./gradlew lint）。

我找到了解决方案，感谢Thomas Keller对his answer的评论。
基本上，我在v21\style.xml文件中使用了自己的对话框样式：
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:alertDialogTheme">@style/MyAlertDialog</item>
<item name="alertDialogTheme">@style/MyAlertDialog</item>
</style>
<style name="MyAlertDialog" parent="Theme.AppCompat.Dialog.Alert">
<item name="colorAccent">?attr/colorAccent</item>
</style>
Google API对话框尝试使用此样式，因此将其从我的xml中删除已修复此问题。
但是，我仍然想使用MyAlertDialog（其colorAccent值），所以有人知道我必须添加哪些颜色才能安抚Google API对话框（以及其他任何内容）谷歌/系统对话框）？
