我正在尝试使用react native和fbsdk wrapper https://github.com/facebook/react-native-fbsdk在Android上设置fbsdk。我有它在iOS上工作，但我被困在Android上。我按照github自述文件执行了所有步骤。
MainApplication.java
@Override
public void onCreate() {
super.onCreate();
FacebookSdk.sdkInitialize(getApplicationContext());
SoLoader.init(this, /* native exopackage */ false);
}
的strings.xml
<resources>
<string name="app_name">FacebookLogin</string>
<string name="facebook_app_id">1343643482425305</string>
<string name="fb_login_protocol_scheme">fb1343643482425305</string>
</resources>
的AndroidManifest.xml
<meta-data android:name="com.facebook.sdk.ApplicationId"
android:value="@string/facebook_app_id"/>
但是我从LogCat
收到此错误11-22 06:57:13.236 7570-7570/? I/zygote: Not late-enabling -Xcheck:jni (already on)

在我的情况下，元数据位于应用程序范围之外。通常，它应位于清单中，如下所示：
<application>
...
<meta-data
android:name="com.facebook.sdk.ApplicationId"
android:value="@string/facebook_app_id" />
</application>

在build.gradle（Module：app）文件中添加以下内容：
repositories {
mavenCentral()
}
和
compile 'com.facebook.android:facebook-android-sdk:4.10.0'
现在在AndroidManifest.xml文件中添加以下内容：
<activity android:name="com.facebook.FacebookActivity"
android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"
android:theme="@android:style/Theme.Translucent.NoTitleBar"
android:label="@string/app_name" />
在activity_main.xml文件中添加以下内容：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.demonuts.fblogin.MainActivity">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#000"
android:layout_marginLeft="10dp"
android:textAppearance="?android:attr/textAppearanceMedium"
android:id="@+id/text"/>
<com.facebook.login.widget.LoginButton
android:id="@+id/btnfb"
android:layout_gravity="center_horizontal"
android:layout_marginTop="10dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>

尝试替换：
const CityPicker = ({ handleCityChange }) => {
const [allCities, setAllCities] = useState([]);
const [states, setStates] = useState([]);
const [counties, setCounties] = useState(null);
useEffect(() => {
const fetchAPI = async () => {
const cities = await fetchCity();
setAllCities(cities);
setStates([...new Set(cities.map(city => city.province))]);
};
fetchAPI();
}, []);
function handleSelectState = function(state) {
setCounties([
...new Set(allCities
.filter(city => city.province === state)
.map(city => city.county)
)
]);
};
return (
<FormControl className={styles.formControl}>
<NativeSelect
defaultValue=" "
onChange={e => handleSelectState(e.target.value)}
>
<option value="">States</option>
{states.map((state, i) => (
<option key={i} value={state}>
{state}
</option>
))}
</NativeSelect>
{ counties &&
<NativeSelect defaultValue=" ">
<option value="">States</option>
{counties.map((county, i) => (
<option key={i} value={county}>
{county}
</option>
))}
</NativeSelect>
}
</FormControl>
);
};
export default CityPicker;
