我有一个问题.我有项目,然后我复制粘贴到另一个新项目,我正面临这个错误

类Call不需要类型参数

在第一个项目中,我没有任何问题......这是我的接口类,我有错误

interface ApiInterface {
    @GET("data/2.5/weather?q=Prague")
    fun getWeatherData(@Query("units") units: String,
                       @Query("appid") appId: String)
            :Call<WeatherData> //here is the error

}

这是我的WeatherData类

data class WeatherData(
        @SerializedName("coord") val coord: Coord,
        @SerializedName("weather") val weather: List<Weather>,
        @SerializedName("base") val base: String,

我想使用MultiSelectListPreference创建一个项目数组并在xml中搜索它们.

我用XML创建了MultiSelectListPreference(res/xml/preferences.xml)

<MultiSelectListPreference
            android:dialogTitle="@string/coursesTitle"
            android:key="searchedCourses"
            android:summary=""        
            android:title="@string/coursesTitle"
            android:entries="@array/courses"
            android:entryValues="@array/courses"
            android:defaultValue="@array/empty_array"
            android:dependency="own_courses"
           />

我创建了一个偏好片段和一个偏好活动.我已经可以选择我想要搜索的项目了.

现在我想读出所选项目.

我试过了

SharedPreferences sharedPref =   PreferenceManager.getDefaultSharedPreferences(this);
 String rawval = sharedPref.getString("searchedCourses", "NA");
 String[] selected = this(context, null).parseStoredValue(rawval);

 Toast.makeText(context, selected[0], Toast.LENGTH_LONG).show();

和我在网上找到的类似"解决方案",但它不起作用.

我在我的项目中包含的库遇到了一些麻烦:一开始它只是一个冲突的依赖性问题,我通过排除 support-v4哪个是共同的共享模块来解决.

问题是其中一个lbsLib-release似乎是.jar在开发人员构建之前在根项目中使用普通文件构建的.

通过运行./gradlew app:dependencies我验证了构建图中没有引用依赖项.

我发现它support-v4嵌入了classes.jar位于:app/build/intermedites/exploded-aar/MyQaaAndroid/lbsLib-release/unspecified/classes.jar/如下图所示:

我不能自己重建项目,因为它不是一个开源的lib,所以有两个问题:

1. 如果我添加compile 'com.android.support:support-v4:18.0.+'到build.gradle一个multiple dex file错误是在编译的时候,因此库引用了两次抛出.

   UNEXPECTED TOP-LEVEL EXCEPTION: com.android.dex.DexException: Multiple dex files define Landroid/support/v4/app/BackStackState;

   Run Code Online (Sandbox Code Playgroud)

   `

2. 如果我删除所有需要support-v4它的库,则会在应用程序运行时抛出缺少的依赖项错误.

所以我想知道是否有可能.jar从构建中排除此文件或使其他libs取决于lbsLib-release嵌入式support-v4 .jar.

compile (project(':lbsLib-release')) {
    exclude module: 'support-v4'
}

compile ('com.sothree.slidinguppanel:library:2.0.4'){ …

你可以帮我解决Android 3.0中的Gradle构建问题吗？

我是Android Studio新手.以下是我在AS 3.0中的配置:

gradle-> wrapper-> gradle-wrapper.properties:

build.gradle依赖项(Gradle的Android插件):

我使用react native创建了一个应用程序.我正在尝试在我的设备上安装该应用程序.但是显示此错误"app not installed -package似乎已损坏".

那是什么原因？我尝试了以下方法来构建apk.

gradlew assembleRelease.

我在我的应用程序中添加了使用firebase身份验证的facebook登录,但登录身份验证仅适用于Android API 24.

当我尝试使用较低级别的API时,屏幕会冻结,应用程序将停止工作.

它太高,大多数用户的API级别较低.

实际上,我打算发布较低API级别的应用程序.

我正在使用的代码如下.

public class ConfigurationActivity extends Activity {

    Button b_v_mm,b_som;
    LoginButton loginButton;
    CallbackManager callbackManager;

    // [START declare_auth]
    private FirebaseAuth mAuth;
    // [END declare_auth]


    private void handleFacebookAccessToken(AccessToken token) {
        Log.d("FireBase", "handleFacebookAccessToken:" + token);

        AuthCredential credential = FacebookAuthProvider.getCredential(token.getToken());
        mAuth.signInWithCredential(credential)
                .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                    @Override
                    public void onComplete(@NonNull Task<AuthResult> task) {
                        if (task.isSuccessful()) {
                            // Sign in success, update UI with the signed-in user's information
                            Log.d("FireBase", "signInWithCredential:success");
                            FirebaseUser user = mAuth.getCurrentUser();
                            //updateUI(user);
                        } else {

ES Strings的XML资源文件有一些更新.使用这些String更改后,Build失败并显示以下错误:

Error:com.github.javaparser.TokenMgrError: Lexical error at line 5563, column 57.  Encountered: "\u00b3" (179), after : ""

该错误表明该问题与Superscript char\u00b3有关,但是,我没有在资源文件中添加它.

要调试此问题,我使用stacktrace直接从终端运行Gradlew,它提供了以下详细信息:

将targetSdkVersion更新为27后,我收到此错误消息.

所有com.android.support库必须使用完全相同的版本规范(混合版本可能导致运行时崩溃).发现版本27.0.2,25.2.0.例子包括com.android.support:animated-vector-drawable:27.0.2和com.android.support:support-media-compat:25.2.0

我知道我应该更新,com.android.support:support-media-compat但我不知道如何因为我没有在build.gradle中使用它,我试图更新SDK工具,但问题仍然存在.bellow是build.gradle:

    apply plugin: 'com.android.application'

    compileSdkVersion 27
    defaultConfig {
        applicationId "com.example.ex"

我想使用带有角度材质表的虚拟滚动条。而且我不想使用分页功能。我的代码如下。
