[Phonegap + Sencha Touch] mobile development 29 Android navigator. camera. getPicture gets the true path of the image,

The phonegap photo plug-in selects the image in the Image Library. The Code is as follows:

Navigator. camera. getPicture (function (uri) {console. log (uri); // uri of the image obtained here}, function (err) {console. log (err) ;},{ quality: 70, destinationType: navigator. camera. destinationType. FILE_URI, sourceType: navigator. camera. pictureSourceType. PHOTOLIBRARY, saveToPhotoAlbum: true });

The returned image path is as follows:

Before Android 4.4: content: // media/external/images/media/62

Android 4.4: content: // com.android.providers.media.doc uments/document/image: 62

This path is called Content URI and is not the actual path of the image. The actual path should be file: // storage/emulated/0/DCIM/Camera/1406773746740.jpg.

Solution:

Open the plug-in file org. apache. cordova. camera \ src \ android \ CameraLauncher. java.

Add the following code:

/** * Get a file path from a Uri. This will get the the path for Storage Access * Framework Documents, as well as the _data field for the MediaStore and * other file-based ContentProviders. * * @param context The context. * @param uri The Uri to query. * @author paulburke */@SuppressLint("NewApi")public static String getPath(final Context context, final Uri uri) {    final boolean isKitKat = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT;    // DocumentProvider    if (isKitKat && DocumentsContract.isDocumentUri(context, uri)) {        // ExternalStorageProvider        if (isExternalStorageDocument(uri)) {            final String docId = DocumentsContract.getDocumentId(uri);            final String[] split = docId.split(":");            final String type = split[0];            if ("primary".equalsIgnoreCase(type)) {                return Environment.getExternalStorageDirectory() + "/" + split[1];            }            // TODO handle non-primary volumes        }        // DownloadsProvider        else if (isDownloadsDocument(uri)) {            final String id = DocumentsContract.getDocumentId(uri);            final Uri contentUri = ContentUris.withAppendedId(                    Uri.parse("content://downloads/public_downloads"), Long.valueOf(id));            return getDataColumn(context, contentUri, null, null);        }        // MediaProvider        else if (isMediaDocument(uri)) {            final String docId = DocumentsContract.getDocumentId(uri);            final String[] split = docId.split(":");            final String type = split[0];            Uri contentUri = null;            if ("image".equals(type)) {                contentUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;            } else if ("video".equals(type)) {                contentUri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;            } else if ("audio".equals(type)) {                contentUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;            }            final String selection = "_id=?";            final String[] selectionArgs = new String[] {                    split[1]            };            return getDataColumn(context, contentUri, selection, selectionArgs);        }    }    // MediaStore (and general)    else if ("content".equalsIgnoreCase(uri.getScheme())) {        // Return the remote address        if (isGooglePhotosUri(uri))            return uri.getLastPathSegment();        return getDataColumn(context, uri, null, null);    }    // File    else if ("file".equalsIgnoreCase(uri.getScheme())) {        return uri.getPath();    }    return null;}/** * Get the value of the data column for this Uri.

Then find the following code:

if (this.targetHeight == -1 && this.targetWidth == -1 &&        (destType == FILE_URI || destType == NATIVE_URI) && !this.correctOrientation) {    this.callbackContext.success(uri.toString());}

Modify to this

if (this.targetHeight == -1 && this.targetWidth == -1 &&        (destType == FILE_URI || destType == NATIVE_URI) && !this.correctOrientation) {    Context context = this.webView.getContext().getApplicationContext();    this.callbackContext.success(getPath(context, uri));}

Remember to import the package at the top:

import android.annotation.SuppressLint;import android.content.ContentUris;import android.content.Context;import android.os.Build;import android.provider.DocumentsContract;
