Question

我正在开发一个Android应用程序以从地图上选择一个地点，并使用Google places API根据位置显示感兴趣的地方。我正在使用PlacePicker Inentbuilder来完成此操作。

但是，运行该应用程序时，地点选择器屏幕会启动，然后立即关闭（大约1-2秒）。

我已经为Android应用程序生成了公共API密钥，并将其包含在应用程序清单的meta-data标签中。

我已在开发人员控制台上启用了“ Google Places API”和“ Android的Google Maps” API。

我在build.gradle的依赖项中包括了最新的Play服务版本。

我在下面包含了我的代码。让我知道是否需要添加其他内容。

这是我的MainActivity.java

public class MainActivity extends AppCompatActivity implements GoogleApiClient.OnConnectionFailedListener {

private GoogleApiClient mGoogleApiClient;
private int PLACE_PICKER_REQUEST = 1;
private TextView tvPlaceDetails;
private FloatingActionButton fabPickPlace;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    initViews();

    mGoogleApiClient = new GoogleApiClient
            .Builder(this)
            .addApi(Places.GEO_DATA_API)
            .addApi(Places.PLACE_DETECTION_API)
            .enableAutoManage(this, this)
            .build();


    fabPickPlace.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            PlacePicker.IntentBuilder builder = new PlacePicker.IntentBuilder();
            try {
                startActivityForResult(builder.build(MainActivity.this), PLACE_PICKER_REQUEST);
            } catch (GooglePlayServicesRepairableException | GooglePlayServicesNotAvailableException e) {
                e.printStackTrace();
            }
        }
    });
}

private void initViews() {
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    fabPickPlace = (FloatingActionButton) findViewById(R.id.fab);
    tvPlaceDetails = (TextView) findViewById(R.id.placeDetails);
}

@Override
protected void onStart() {
    super.onStart();
    mGoogleApiClient.connect();
}

@Override
protected void onStop() {
    mGoogleApiClient.disconnect();
    super.onStop();
}

@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
    Snackbar.make(fabPickPlace, connectionResult.getErrorMessage() + "", Snackbar.LENGTH_LONG).show();
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == PLACE_PICKER_REQUEST) {
        if (resultCode == RESULT_OK) {
            Place place = PlacePicker.getPlace(data, this);
            StringBuilder stBuilder = new StringBuilder();
            String placename = String.format("%s", place.getName());
            String latitude = String.valueOf(place.getLatLng().latitude);
            String longitude = String.valueOf(place.getLatLng().longitude);
            String address = String.format("%s", place.getAddress());
            stBuilder.append("Name: ");
            stBuilder.append(placename);
            stBuilder.append("\n");
            stBuilder.append("Latitude: ");
            stBuilder.append(latitude);
            stBuilder.append("\n");
            stBuilder.append("Logitude: ");
            stBuilder.append(longitude);
            stBuilder.append("\n");
            stBuilder.append("Address: ");
            stBuilder.append(address);
            tvPlaceDetails.setText(stBuilder.toString());
        }
    }
}
}

这是我的Manifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.androidmads.placepickersample">

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

<uses-permission android:name="android.permission.INTERNET" />

<application

    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">

    <meta-data
        android:name="com.google.android.geo.API_KEY"
        android:value="AIzaSyAEangx6jaBLULaI-QoGON7R-TwIUQSRjg"/>

    <meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:theme="@style/AppTheme.NoActionBar">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

这是我的Build.Gradle：

apply plugin: 'com.android.application'
android {
compileSdkVersion 28
buildToolsVersion "28.0.3"
defaultConfig {
    applicationId "com.androidmads.placepickersample"
    minSdkVersion 15

    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    multiDexEnabled true
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'

testImplementation 'junit:junit:4.12'
implementation 'com.google.android.libraries.places:places:1.0.0'

implementation 'com.google.android.gms:play-services:9.2.0'
}

任何人都可以帮助我

启动后，Android Place Picker屏幕立即关闭
