我的项目在 AVD 上正确运行。但是当我尝试生成签名的 APK 时，gradle 出现此错误：

FAILURE: Build failed with an exception.

* What went wrong:
java.lang.IllegalStateException: Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 2 path $
> Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 2 path $

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more 
log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

我已经多次使用这个命令：gson.fromJson. …

错误:我想将Realm数据库从版本4.2.0更新到4.3.3,但在gradle sync之后,它将失败

目标

将Realm从4.2.0更新到4.3.3

预期成绩

Gradle sync将成功

实际结果

gratra同步失败,堆栈跟踪:

Error:Execution failed for task ':QuizApp:processDebugResources'.
Could not get unknown property 'packageForR' for task 
':QuizApp:processDebugResources' of type

我将我的项目从Eclipse导入Android Studio V2.2.2.但是当Gradle构建完成后,我在Logcat中出现了这个错误,并在模拟器上显示了一个白色屏幕5-10秒.我有所有可用的解决方案,但到目前为止我还没有找到解决这个问题的方法.我提前为可怜的英语道歉.

我的LogCat应用程序开始运行时:

和我的模拟器屏幕:

在我将Android工作室从2.3.3更新到3.0后,编译并运行后出现此错误(rror inflating class com.astuetz.PagerSlidingTabStrip)请参阅下面的日志错误:

我将Picasso用作我的App项目和聊天库的依赖项

这是我在编译代码时遇到的错误：

程序类型已存在：org.apache.http.auth.AuthSchemeFactory消息{种类=错误，文本=程序类型已存在：

org.apache.http.auth.AuthSchemeFactory，来源= [未知源文件]，工具名称= Optional.of（D8）}

那么如何对两个项目使用相同的依赖关系？

在app> libs文件夹中，jar存在以下文件：

• httpclient-4.3.6
• httpcore-4.3.3
• httpmime-4.3.6

我正在使用Android Studio 3.5 Canary 7。当我调试项目时，菜单中的“ 应用代码更改 ”被禁用。一次，这对我的项目有效，但今天却没有。我应检查哪些设置以使其起作用？

我尝试通过以下代码隐藏NavigationBar:

public static void setFullscreen(final View decorView) {
    decorView.setOnSystemUiVisibilityChangeListener(new View.OnSystemUiVisibilityChangeListener() {
        @Override
        public void onSystemUiVisibilityChange(int visibility) {
            if ((visibility & View.SYSTEM_UI_FLAG_FULLSCREEN) == 0) {
                decorView.setSystemUiVisibility(
                        View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                                | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                                | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                                | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                                | View.SYSTEM_UI_FLAG_FULLSCREEN
                                | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
            }

        }
    });

    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.JELLY_BEAN) {
        decorView.setSystemUiVisibility(decorView.getSystemUiVisibility());
    }
}

并为每个活动:

@Override
public void onWindowFocusChanged(boolean hasFocus) {
    super.onWindowFocusChanged(hasFocus);
    if (hasFocus) {
        getWindow().getDecorView().setSystemUiVisibility(
                View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                        | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                        | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                        | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                        | View.SYSTEM_UI_FLAG_FULLSCREEN
                        | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);}
}
