我试图重振我在2014年制作的旧Google地图应用。除了一个之外没有任何问题:尝试在我在上面调用的自定义方法中初始化地图同一个班级,我收到这个错误:
java.lang.NoSuchMethodError: No virtual method getMapAsync(Lcom/google/android/gms/maps/OnMapReadyCallback;)V in class Lcom/google/android/gms/maps/MapFragment; or its super classes (declaration of 'com.google.android.gms.maps.MapFragment' appears in /data/data/com.packagename.appname/files/instant-run/dex/slice-google-play-services_013f7ca48f60d837bd691f2b8fafce962adefa56-classes.dex)
这是方法本身:
private void initilizeMap()
{
if (mGoogleMap == null) {
MapFragment mapFragment = (MapFragment) getFragmentManager().findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
== PackageManager.PERMISSION_GRANTED) {
mGoogleMap.setMyLocationEnabled(true);
} else {
Toast.makeText(this, "You have to accept to enjoy all app's services!", Toast.LENGTH_LONG).show();
}
}
}
方法initializeMap()在其声明之上调用,Android Monitor指向该行以及该行:
MapFragment mapFragment = (MapFragment) getFragmentManager().findFragmentById(R.id.map);
片段在布局中正确声明。另外,在下面,我已经覆盖了mapReady上的方法:
@Override
public void onMapReady(GoogleMap googleMap)
{
mGoogleMap = googleMap;
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
== PackageManager.PERMISSION_GRANTED) {
mGoogleMap.setMyLocationEnabled(true);
}
}
我不知道造成这个问题的原因。
EDIT(build.gradle依赖项):
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.1.0'
compile 'com.android.support:design:25.1.0'
compile 'com.google.maps.android:android-maps-utils:0.4+'
testCompile 'junit:junit:4.12'
compile files('libs/android-google-maps-api13.jar')
compile 'com.google.android.gms:play-services:8.4.0'
apply plugin: 'com.google.gms.google-services'
compile files('libs/google-play-services.jar')
compile 'com.google.android.gms:play-services-maps:8.4.0'
}
答案 0 :(得分:0)
您在运行时看到的MapFragment
实例没有预期的方法。看起来您使用较新版本进行编译,然后用于运行应用程序。
