[英]Why does not permitted in android ? using react-native-image-picker
i have a problem.我有个问题。 i had added codes for permitting about 'image'
我添加了允许“图像”的代码
<uses-permission android:name="android.permission.CAMERA"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
but, i had a console.log like below,但是,我有一个如下所示的 console.log,
Response = {error: "Permissions weren't granted"}
Why i had a problem that i had added codes for permitting code to /android/src/main/AndroidManifest.xml?为什么我在 /android/src/main/AndroidManifest.xml 中添加了允许代码的代码?
below the entity code of the component在组件的实体代码下方
import ImagePicker from "react-native-image-picker";
...
const [url, setUrl] = useState(null);
...
<Button title={"Upload Image"} onPress={() => {
ImagePicker.showImagePicker(options, (response) => {
console.log("Response = ", response);
if (response.didCancel) {
console.log("User cancelled image picker");
} else if (response.error) {
console.log("ImagePicker Error: ", response.error);
} else if (response.customButton) {
console.log("User tapped custom button: ", response.customButton);
} else {
// const source = { uri: response.uri };
// You can also display the image using data:
// const source = { uri: 'data:image/jpeg;base64,' + response.data };
setUrl("data:image/jpeg;base64," + response.data);
}
});
}}/>
{url && (
<Image source={{uri:url}} style={{width:340, height:340}} />
)}
below the entity code of android/src/main/AndroidManifest.xml在android/src/main/AndroidManifest.xml的实体代码下面
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.sampleapp">
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.CAMERA"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<application
android:name=".MainApplication"
android:label="@string/app_name"
android:icon="@mipmap/ic_launcher"
android:roundIcon="@mipmap/ic_launcher_round"
android:allowBackup="false"
android:theme="@style/AppTheme">
<activity
android:name=".MainActivity"
android:label="@string/app_name"
android:configChanges="keyboard|keyboardHidden|orientation|screenSize|uiMode"
android:launchMode="singleTask"
android:windowSoftInputMode="adjustResize">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="com.facebook.react.devsupport.DevSettingsActivity" />
</application>
</manifest>
before picking image, ask permission to user..在选择图像之前,请征得用户许可..
const requestCameraPermission = async () => {
try {
const granted = await PermissionsAndroid.request(
PermissionsAndroid.PERMISSIONS.CAMERA,
{
title: "Cool Photo App Camera Permission",
message:
"Cool Photo App needs access to your camera " +
"so you can take awesome pictures.",
buttonNeutral: "Ask Me Later",
buttonNegative: "Cancel",
buttonPositive: "OK"
}
);
if (granted === PermissionsAndroid.RESULTS.GRANTED) {
console.log("You can use the camera");
} else {
console.log("Camera permission denied");
}
} catch (err) {
console.warn(err);
}
};
