引起：java.lang.IllegalStateException：应用程序的AndroidManifest.xml中不需要的元数据标记不存在。您必须在元素中包含以下声明：
app.gradle
dependencies {
compile 'io.nlopez.smartlocation:library:3.3.1'
compile 'com.android.support:appcompat-v7:25.2.0'
compile 'com.android.support:support-v4:25.2.0'
compile 'com.loopj.android:android-async-http:1.4.9'
compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.5'
compile 'com.google.firebase:firebase-messaging:10.2.1'
compile 'com.google.firebase:firebase-ads:10.2.1'
compile 'com.google.android.gms:play-services-location:10.2.1'
compile 'com.google.firebase:firebase-crash:9.6.0'
compile 'com.google.android.gms:play-services:10.2.1'
}
当我用Google搜索时，我得到了以下答案
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
但我收到一条错误，指出@ integer / google_play_services_version无法解析符号 我也得到了如果我使用最新的编译'com.google.android.gms：play-services：10.2.1' 并且无需定义元数据
我收到以下代码的错误
public boolean isGooglePlayServicesAvailable(Activity activity) {
GoogleApiAvailability googleApiAvailability = GoogleApiAvailability.getInstance();
int status = googleApiAvailability.isGooglePlayServicesAvailable(activity);
if (status != ConnectionResult.SUCCESS) {
if (googleApiAvailability.isUserResolvableError(status)) {
googleApiAvailability.getErrorDialog(activity, status, 2404).show();
}
return false;
}}
现在有人可以帮我解决这个问题吗？
