我正试图用相机拍照,但我收到以下错误:

FATAL EXCEPTION: main
Process: com.example.marek.myapplication, PID: 6747

AndroidManifest.xml中:

<provider
        android:name="android.support.v4.content.FileProvider"
        android:authorities="com.example.marek.myapplication.fileprovider"
        android:enabled="true"

            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/file_paths" />
</provider>

Java的:

Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    // Ensure that there's a camera activity to handle the intent
    if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
        // Create the File where the photo should go
        File photoFile = null;
        try {
            photoFile = createImageFile();
        } catch …

有人面临下面的问题吗？可以为此提供帮助.目前的gradle版本4.4 in dist

找不到org.jetbrains.kotlin:kotlin-gradle-plugin:1.2.50-eap-62.在以下位置搜索:

我尝试在Android Studio 1.5.1中使用espresso 2.2.1运行测试.当我运行LoginActivityTest时,我收到此错误:当LoginActivity调用MyService.java并且MyService需要整数资源(即R.integer.number_of_days)时,会导致"android.content.res.Resources $ NotFoundException".此资源在gradle(版本1.5.0)模块的R.integer.xml文件中定义.

public LoginActivityTest() {

今天，我将Jenkins版本从2.151更新为2.152（在我的ec2实例中），我遇到的第一个错误是 java.lang.NoClassDefFoundError: com/trilead/ssh2/crypto/Base64

我收到此错误：

有人有解决这个问题的想法吗？

我有一个简单的场景，我在片段中做一些事情，当我收到 LiveData 时，我想在 Activity 中做一些事情。

视图模型：

class MyViewModel(application: Application) : AndroidViewModel(application) {
    
   ...
    
    fun getUser(id: String): LiveData<User> {
        return repository.getUser(id)
    }
}

分段：

class MyFragment : Fragment() {

    private lateinit var myViewModel: MyViewModel

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        activity?.run {
            myViewModel = ViewModelProviders.of(this).get(MyViewModel::class.java)
        } ?: throw Exception("Invalid Activity")
    }

    override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
        return inflater.inflate(R.layout.fragment, container, false)
    }

    override fun onActivityCreated(savedInstanceState: Bundle?) {
        super.onActivityCreated(savedInstanceState)
        button.setOnClickListener {
            showProgressBar()
            myViewModel.getUser(editText.text.toString()).observe(this, Observer { it ->
                //TODO …

我正在关注这个 Google Codelab，在第8 页（任务：使用数据绑定进行端到端测试），在第 8 步（编写 DataBindingIdlingResource），您必须创建一个名为DataBindingIdlingResource.kt.

class DataBindingIdlingResource : IdlingResource {
    [...]
}

private fun View.getBinding(): ViewDataBinding? = DataBindingUtil.getBinding(this)

/**
 * Sets the activity from an [ActivityScenario] to be used from [DataBindingIdlingResource].
 */
fun DataBindingIdlingResource.monitorActivity(
    activityScenario: ActivityScenario<out FragmentActivity>
) {
    activityScenario.onActivity {
        this.activity = it
    }
}

/**
 * Sets the fragment from a [FragmentScenario] to be used from [DataBindingIdlingResource].
 */
fun DataBindingIdlingResource.monitorFragment(fragmentScenario: FragmentScenario<out Fragment>) {
    fragmentScenario.onFragment {
        this.activity = it.requireActivity() …

这是我的布局 xml

<TextView
    android:id="@+id/loginTextView"
    android:layout_width="255dp"
    android:layout_height="60dp"
    android:layout_marginBottom="15dp"
    android:background="@drawable/sign_in_login_bg"
    android:gravity="center"                              
    app:layout_constraintBottom_toTopOf="@+id/registerTextView"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent" />

这里@drawable/sign_in_login_bg

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="@color/color_primary" />
    <corners android:radius="@dimen/text_view_rounded_corner_radius" />
</shape>

我想编写浓缩咖啡测试来检查loginTextView是否具有背景@drawable/sign_in_login_bg

所以我写了自定义匹配器：

import org.hamcrest.Matcher;
public static Matcher<View> withBackground(final int expectedResourceId) {
        
      return new BoundedMatcher<View, View>(View.class) {
        
          @Override
          public boolean matchesSafely(View view) {
              return sameBitmap(view.getContext(), view.getBackground(), expectedResourceId);
         }
        
         @Override
         public void describeTo(Description description) {
             description.appendText("has background resource " + expectedResourceId);
        }
    };
} …
