Android开发新手。我创建了一个" Hello World" Android Studio中的项目(版本1.3.1)。我正在尝试如何显示日志并查看应用程序如何运行。以下是我在MainActivity.java中的内容,它是由Android Studio自动创建的,我只添加了Log标记。
public class MainActivity extends AppCompatActivity {
private static final String TAG = "MjMessageFromActivities"
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Log.i(TAG, "onCreate");
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
当我运行应用程序以查看DDMS中的日志时,我收到以下三个错误:
Error:(2) Error retrieving parent for item: No resource found that matches the given name 'android:TextAppearance.Material.Widget.Button.Inverse'
Error:(2) Error retrieving parent for item: No resource found that matches the given name 'android:Widget.Material.Button.Colored'
Error:Execution failed for task ':app:processDebugResources'.
> com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Users\smart\AppData\Local\Android\sdk\build-tools\23.0.0\aapt.exe'' finished with non-zero exit value 1
这是build.gradle内容:
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.3.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
}
}
请您指导我如何修复上述错误以查看日志?
