我在更新后更新了android SDK到android预览版N,我收到了这个xml渲染错误.点击详细信息后,它显示以下堆栈跟踪如何避免这种情况

我最近将Android Studio从2.2.3更新到2.3.现在看不到"启动独立SDK管理器"选项,这对检查更新,谷歌播放服务等很有用.

我已在 Macbook 中将 Android Studio 更新到 4.1，但更新后无法运行应用程序。它给出了以下错误

Execution failed for task ':app:stripDebugDebugSymbols'.
NDK at ~/Library/Android/sdk/ndk-bundle did not have a source.properties file

设置compile 'com.google.android.gms:play-services-appindexing:10.0.0'它时会出现以下错误:

Error:(82, 13) Failed to resolve: com.google.android.gms:play-services-appindexing:10.0.0

并在设置compile 'com.google.android.gms:play-services-appindexing:9.8.0'它时给出以下错误:

Error:Execution failed for task ':app:processDebugGoogleServices'.
> Please fix the version conflict either by updating the version of the google-services plugin (information about the latest version is available at https://bintray.com/android/android-tools/com.google.gms.google-services/) or updating the version of com.google.android.gms to 10.0.0.

如果有人能告诉我这是错误的,那将是非常感激的,因为休息游戏服务版本10.0.0正常工作.

我的build.gradle文件

buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }

    dependencies {
        classpath 'io.fabric.tools:gradle:1.22.0'
    }
}
apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

android {
    signingConfigs {

    } …

我正在尝试使用此处所述的ActivityResult APIs ActivityResult APIs

但它给出了未解决的参考错误。

我正在使用以下依赖项

api 'androidx.activity:activity:1.1.0'
api 'androidx.activity:activity-ktx:1.1.0'
api 'androidx.fragment:fragment:1.2.5'
api 'androidx.fragment:fragment-ktx:1.2.5'

我已经将编译SDK和目标SDK版本更新到android P但是在更新应用程序无法安装之后,即使从我的设备卸载旧版本的APK后,也会给出相同的错误弹出窗口.

我的build.gradle设置:

compileSdkVersion 'android-P'
    defaultConfig {
        applicationId "com.my.app"
        minSdkVersion 15
        targetSdkVersion 'P'
        versionCode 31
        versionName "1.2.14"
        multiDexEnabled true
        vectorDrawables.useSupportLibrary = true
    }

当我在红米7A上启动相机拍照时，我的应用程序自动崩溃。以下是崩溃日志：

   E/CAM_CameraIntentManager: checkCallerLegality: Unknown caller: com.qikcircle.eclinic

请帮助它确实没有显示到底是什么问题。

我的活动代码

class CaptureImageActivity : AppCompatActivity() {

    private lateinit var mToolbar: Toolbar
    private lateinit var mImage: ImageView
    private var mBitmap: Bitmap? = null

    private val getCameraAndStoragePermission = registerForActivityResult(
            ActivityResultContracts.RequestMultiplePermissions()) { permissions ->
        if (hasAllPermissionsGranted(permissions)) {
            dispatchTakePictureIntent()
        } else {
            Toast.makeText(
                    this,
                    resources.getString(R.string.allow_camera_permission),
                    Toast.LENGTH_SHORT)
                    .show()
            finish()
        }
    }

    private val takePicture =
            registerForActivityResult(ActivityResultContracts.TakePicture()) { success ->
        if (success) {
            photoURI.let {
                mBitmap = getBitmap(this, photoURI)
                mImage.setImageBitmap(mBitmap)
                goBack()
            }
        } else {

我已经更新了Retrofit v 2.3.0和okhttp 3.8.0和okio 1.13.0但是现在我正在尝试生成签名的APK时出现以下错误:

Warning:retrofit2.OkHttpCall: can't find referenced class javax.annotation.concurrent.GuardedBy
Warning:there were 3 unresolved references to classes or interfaces.
Warning:Exception while processing task java.io.IOException: Please correct the above warnings first.
Error:Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease'.

Job failed, see logs for details 

以下是我用于Retrofit和OKHTTP的程序规则

# Platform calls Class.forName on types which do not exist on Android to determine platform.
-dontnote retrofit2.Platform
# Platform used when running on Java 8 VMs. Will not be used at runtime.
-dontwarn retrofit2.Platform$Java8
# Retain generic …

我已经将支持库更新到23.2.1,之后回收物品项目出现了很大的空白区域.虽然我使用的是recyclerview,它的父视图高度为WRAP_CONTENT.我的应用程序一次从服务器获取10个项目数据,当向上滚动时,它在底部显示一个进度条,所以当时(当显示进度条时)recyclelerview项目显示的空间非常大.

片段和适配器的xml文件代码分别为:
