我有

compile 'com.facebook.android:facebook-android-sdk:4.16.0'

我的清单:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
...
    <application
            android:name=".YandexProvider"
            android:allowBackup="true"
            android:icon="@drawable/ic_launcher"
            android:label="@string/app_name"
            android:theme="@style/AutoTheme"
            tools:replace="android:theme">

如何解决编译错误:

Error:Execution failed for task ':app:processDebugManifest'.
> Manifest merger failed : Attribute activity#com.facebook.FacebookActivity@theme value=(@android:style/Theme.Translucent.NoTitleBar) from AndroidManifest.xml:69:13-72
    is also present at [com.facebook.android:facebook-android-sdk:4.16.0] AndroidManifest.xml:32:13-63 value=(@style/com_facebook_activity_theme).
    Suggestion: add 'tools:replace="android:theme"' to <activity> element at AndroidManifest.xml:66:9-70:47 to override.

我有两个正在运行的模拟器，但它们在不同的选项卡和一个窗口中一起打开。

如何在两个不同的窗口中打开它们？

我有这样的回答:

{
 "songs":{
          "2562862600":{"id":"2562862600""pos":1},
          "2562862620":{"id":"2562862620""pos":1},
          "2562862604":{"id":"2562862604""pos":1},
          "2573433638":{"id":"2573433638""pos":1}
         }
 }

这是我的代码:

List<NameValuePair> param = new ArrayList<NameValuePair>();
JSONObject json = jParser.makeHttpRequest(url, "GET", param);

JSONObject songs= json.getJSONObject("songs");

我如何转换"songs"为JSONArray？

这里说的是我需要在java上设置Firebase:

FirebaseOptions options = new FirebaseOptions.Builder()
    .setDatabaseUrl("https://databaseName.firebaseio.com")
    .setServiceAccount(new FileInputStream("path/to/serviceAccountCredentials.json"))
    .build();
FirebaseApp.initializeApp(options);

但是我在哪里可以获得serviceAccountCredentials.json？

更新: 我发现这个文件似乎应该有这个字段,但是哪里得到这个值？

{
  "type": "",
  "project_id": "",
  "private_key_id": "",
  "private_key": "",
  "client_email": "",
  "client_id": "",
  "auth_uri": "",
  "token_uri": "",
  "auth_provider_x509_cert_url": "",
  "client_x509_cert_url": ""
}

我正在使用改造.要捕获响应,我正在使用Interceptor:

OkHttpClient okHttpClient = new OkHttpClient();
okHttpClient.interceptors().add(myinterceptor);

这是拦截器的代码:

new Interceptor() {
    @Override
    public Response intercept(Chain chain) throws IOException {
        Request request = chain.request();
        Response response = chain.proceed(request);
        if (path.equals("/user")){
            String stringJson = response.body().string();
            JSONObject jsonObject = new JSONObject(stringJson);
            jsonObject.put("key",1);
            //here I need to set this new json to response and then return this response

如何在OkHttp响应中更改正文？

我有EditView,并希望在代码上更改PROGRAMMATICALLY颜色.

要更改光标的颜色,请使用此代码.

但是如何在代码上的EditView PROGRAMMATICALLY上更改圆圈的颜色？

Android Studio 3.2.1
Kotlin plugin version 1.3.11-release-Studio3.2-1
ext.kotlin_version = '1.3.11' 
RxJava 1.3.0 

例如,当我输入*.kt文件:Observable.unsafeCreate{}然后按两次Ctrl+Space之间{},然后IntellijIdea建议我键入符号t ->,但是当我在.java文件中执行相同的操作时结果是subscriber ->:

*.kt 文件:

fun anyFunc(): Observable<Boolean>{
    return Observable.unsafeCreate { t -> t }
}

*.java 文件:

public void anyFunc() {
    Observable.unsafeCreate(subscriber -> {});
}

如何在Kotlin文件中创建与Java文件中相同的建议输入行为？

[UPDATE] 似乎是因为call()方法rx.functions.Func1,它有param t:

public interface Func1<T, R> extends Function { 
    R call(T t); 
}

我通过以下代码从资产中复制数据库:

    public class DatabaseHelper extends OrmLiteSqliteOpenHelper {
        private static final String DATABASE_NAME = "database.db";
        private static final String DATABASE_PATH = "/data/data/"+BuildConfig.APPLICATION_ID+"/databases/";

     public DatabaseHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
        copyFromAssets(context);
    }

      private void copyFromAssets(Context context) {
        boolean dbexist = checkdatabase();
        if (!dbexist) {
            File dir = new File(DATABASE_PATH);
                dir.mkdirs();
                InputStream myinput = context.getAssets().open(DATABASE_NAME);
                String outfilename = DATABASE_PATH + DATABASE_NAME;
                Log.i(DatabaseHelper.class.getName(), "DB Path : " + outfilename);
                OutputStream myoutput = new FileOutputStream(outfilename);
                byte[] buffer = new byte[1024];

在以下库中: com.google.android.gms:play-services-fitness:9.8.0

在以下课程中: com.google.android.gms.fitness.FitnessActivities

有这种方法: public static java.lang.String getName(int i)

但是,在库com.google.android.gms:play-services-fitness:10.2.0中删除了上述方法.

用什么方法代替上面提到的方法？
