react-native-camera (android): takePictureAsync() throws error


After calling takePictureAsync() from react-native-camera, i'm getting this error:

{
  "framesToPop": 1,
  "nativeStackAndroid": [],
  "userInfo": null,
  "message": "Preview is paused - resume it before taking a picture.",
  "code": "E_TAKE_PICTURE_FAILED",
  "line": 2131,
  "column": 45,
  "sourceURL": "http://10.0.2.2:8081/index.bundle?platform=android&dev=true&minify=false"
}

So I tried using resumePreview() method before calling takePictureAsync() and now I'm getting a different error message:

{
  "framesToPop": 1,
  "nativeStackAndroid": [],
  "userInfo": null,
  "message": "takePicture failed",
  "code": "E_TAKE_PICTURE_FAILED",
  "line": 2131,
  "column": 45,
  "sourceURL": "http://10.0.2.2:8081/index.bundle?platform=android&dev=true&minify=false"
}

My component and usage i identical to that of https://react-native-community.github.io/react-native-camera/docs/rncamera

    <RNCamera
      ref={ref => {
        this.camera = ref;
      }}
      style={styles.preview}
      type={RNCamera.Constants.Type.back}
      flashMode={RNCamera.Constants.FlashMode.on}
      androidCameraPermissionOptions={{
        title: 'Permission to use camera',
        message: 'We need your permission to use your camera',
        buttonPositive: 'Ok',
        buttonNegative: 'Cancel',
      }}
      androidRecordAudioPermissionOptions={{
        title: 'Permission to use audio recording',
        message: 'We need your permission to use your audio',
        buttonPositive: 'Ok',
        buttonNegative: 'Cancel',
      }}
      onGoogleVisionBarcodesDetected={({ barcodes }) => {
        console.log(barcodes);
      }}
    />




takePicture = async () => {
    if (this.camera) {
      const options = { quality: 0.5, base64: true };
      try {
        this.camera.resumePreview();
        const data = await this.camera.takePictureAsync(options);
        console.log(data.uri);
      } catch (error) {
        console.log(JSON.stringify(error, null, 2));
      }
    }
  };

versions:

"react-native": "0.61.2",
"react-native-camera": "git+https://git@github.com/react-native-community/react-native-camera.git",

Works fine on iOS. Is this an issue with the library or my implementation?


Solution

  • Try to use component as FaCC (Function as Child Components)! This way worked for me.

    const PendingView = () => (
      <View
        style={{
          flex: 1,
          backgroundColor: 'lightgreen',
          justifyContent: 'center',
          alignItems: 'center',
        }}
      >
        <Text>Waiting</Text>
      </View>
    );
    
    class ExampleApp extends PureComponent {
      render() {
        return (
          <View style={styles.container}>
            <RNCamera
              style={styles.preview}
              type={RNCamera.Constants.Type.back}
            >
              {({ camera, status, recordAudioPermissionStatus }) => {
                if (status !== 'READY') return <PendingView />;
                return (
                  <View style={{ flex: 0, flexDirection: 'row', justifyContent: 'center' }}>
                    <TouchableOpacity onPress={() => this.takePicture(camera)} style={styles.capture}>
                      <Text style={{ fontSize: 14 }}> SNAP </Text>
                    </TouchableOpacity>
                  </View>
                );
              }}
            </RNCamera>
          </View>
        );
      }
    
      takePicture = async function(camera) {
        const options = { quality: 0.5, base64: true };
        const data = await camera.takePictureAsync(options);
        //  eslint-disable-next-line
        console.log(data.uri);
      };
    }
    
    const styles = StyleSheet.create({
      container: {
        flex: 1,
        flexDirection: 'column',
        backgroundColor: 'black',
      },
      preview: {
        flex: 1,
        justifyContent: 'flex-end',
        alignItems: 'center',
      },
      capture: {
        flex: 0,
        backgroundColor: '#fff',
        borderRadius: 5,
        padding: 15,
        paddingHorizontal: 20,
        alignSelf: 'center',
        margin: 20,
      },
    });
