我已经成功配置了android-P SDK环境.当我尝试使用android设计支持库时,我面临项目构建错误.项目配置是:

IDE:3.2 Canary 17目标API:28编译API:28

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.app.navigationpoc"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'androidx.appcompat:appcompat:1.0.0-alpha3'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.1'

    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.1.0-alpha3'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0-alpha3'

    implementation 'com.android.support:design:28.0.0-alpha3'
    implementation 'com.android.support:cardview-v7:28.0.0-alpha3'
}

并且构建失败的错误是:

清单合并失败:来自[androidx.core:core:1.0.0-alpha3] AndroidManifest.xml:22:18-86的属性应用程序@ appComponentFactory值=(androidx.core.app.CoreComponentFactory)也出现在[com.android] .support:support-compat:28.0.0-alpha3] AndroidManifest.xml:22:18-91 value =(android.support.v4.app.CoreComponentFactory).建议:在AndroidManifest.xml:6:5-40:19中添加'tools:replace ="android:appComponentFactory"'来覆盖.

我已将我的 Android Studio 和targetSdkVersion(build.gradle) 更新为 29。我迁移到了 AndroidX。现在 Gradle 构建给了我这两个错误。

此项目使用 AndroidX 依赖项，但未启用 'android.useAndroidX' 属性。在 gradle.properties 文件中将此属性设置为 true 并重试。

检测到以下 AndroidX 依赖项：androidx.versionedparcelable:versionedparcelable:1.0.0、androidx.fragment:fragment:1.0.0、androidx.slidingpanelayout:slidingpanelayout:1.0.0、androidx.core:core:1.0.0、androidx.customview :customview:1.0.0, androidx.swiperrefreshlayout:swiperrefreshlayout:1.0.0, androidx.interpolator:interpolator:1.0.0, androidx.loader:loader:1.0.0, androidx.drawerlayout:drawerlayout:1.0.0, androidx.viewpage :viewpager:1.0.0, androidx.collection:collection:1.0.0, androidx.localbroadcastmanager:localbroadcastmanager:1.0.0, androidx.lifecycle:lifecycle-common:2.0.0, androidx.arch.core:core-common:2.0 .0, androidx.annotation:annotation:1.1.0, androidx.lifecycle:lifecycle-livedata:2.0.0, androidx.legacy:legacy-support-core-ui:1.0.0, androidx.lifecycle:lifecycle-viewmodel:2.0 .0，androidx.lifecycle:lifecycle-livedata-core:2。0.0, androidx.arch.core:core-runtime:2.0.0, androidx.legacy:legacy-support-core-utils:1.0.0, androidx.documentfile:documentfile:1.0.0, androidx.cursoradapter:cursoradapter:1.0。 0, androidx.lifecycle:lifecycle-runtime:2.0.0, androidx.coordinatorlayout:coordinatorlayout:1.0.0, androidx.asynclayoutinflater:asynclayoutinflater:1.0.0, androidx.print:print:1.0.0

我的代码是：MainActivity.java

package it.manuel.myapp;

import android.Manifest;
import android.app.Activity;
import android.app.AlertDialog;
import android.app.DownloadManager;
import android.app.Notification;
import android.app.NotificationChannel;
import android.app.NotificationManager;
import android.content.DialogInterface;

import android.net.Uri;
import android.os.Build;
import android.support.v4.app.ActivityCompat;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle; …

合并dex时出错

以下是依赖项.

ext {
    anko_version='0.10.5'
    support_lib='1.0.0-alpha1'
    room_lib = "1.1.0"
}
dependencies {

    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version"
    implementation "androidx.cardview:cardview:$support_lib"
    implementation "com.google.android.material:material:$support_lib"
    implementation "androidx.appcompat:appcompat:$support_lib"
    implementation "org.jetbrains.anko:anko:$anko_version"

    implementation "android.arch.persistence.room:runtime:$room_lib"
    annotationProcessor "android.arch.persistence.room:compiler:$room_lib"
}

错误

• 出了什么问题:任务执行失败':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.

  com.android.builder.dexing.DexArchiveMergerException:合并dex存档时出错:/app/build/intermediates/transforms/dexBuilder/debug/0.jar,程序类型已存在:android.support.v4.os.ResultReceiver $ 1

我想定期(比如每2分钟)当前位置更新为这个我下面的官方文档,我写了这个代码,但它不会给当前的位置即使在我传递requestLocationUpdates LocationRequest对象指定每两分钟更新( ),这里是代码:

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback,
    GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener{

private FusedLocationProviderClient FusedLocationClient;
private GoogleApiClient mGoogleApiClient;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_maps);
    if (mGoogleApiClient == null) {
        mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API)
                .build();
    }

 SupportMapFragment map = 
  getSupportFragmentManager().findFragmentById(R.id.map));

  map.getMapAsync(this);

  FusedLocationClient LocationServices.getFusedLocationProviderClient(this);
}


@Override
public void onConnected(Bundle bundle) {
    FusedLocationClient.getLastLocation()
            .addOnSuccessListener(this, new OnSuccessListener<Location>() {
                @Override
                public void onSuccess(Location location) {

                    if (location != null) {
                        Log.i("MainActivity ", "" + location.getLongitude()) 
                    }
                }
            });
FusedLocationClient = …

我想将我的应用程序与 facebook 登录集成，但是在添加以下依赖项并同步 Gradle 时：

implementation 'com.facebook.android:facebook-android-sdk:[5,6)'

我收到以下错误：

        maven { url 'https://plugins.gradle.org/m2/'}
