Android/Java: <input type="file" accept="image/*;capture=camera"> doesn't work anymore in WebView
How can I open the camera from a webview directly in html to take a picture or pick up a gallery photo with android? It seems that the
<input type="file" accept="image/*;capture=camera">
doesn't work anymore...
Here is my code:
main class:
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
if (requestCode != INPUT_FILE_REQUEST_CODE || mFilePathCallback == null) {
super.onActivityResult(requestCode, resultCode, data);
return;
}
Uri[] results = null;
// Check that the response is a good one
if (resultCode == Activity.RESULT_OK) {
if (data == null) {
// If there is not data, then we may have taken a photo
if (mCameraPhotoPath != null) {
results = new Uri[]{Uri.parse(mCameraPhotoPath)};
}
} else {
String dataString = data.getDataString();
if (dataString != null) {
results = new Uri[]{Uri.parse(dataString)};
}
}
}
mFilePathCallback.onReceiveValue(results);
mFilePathCallback = null;
} else if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.KITKAT) {
if (requestCode != FILECHOOSER_RESULTCODE || mUploadMessage == null) {
super.onActivityResult(requestCode, resultCode, data);
return;
}
if (requestCode == FILECHOOSER_RESULTCODE) {
if (null == this.mUploadMessage) {
return;
}
Uri result = null;
try {
if (resultCode != RESULT_OK) {
result = null;
} else {
// retrieve from the private variable if the intent is null
result = data == null ? mCapturedImageURI : data.getData();
}
} catch (Exception e) {
Toast.makeText(getApplicationContext(), "activity :" + e,
Toast.LENGTH_LONG).show();
}
mUploadMessage.onReceiveValue(result);
mUploadMessage = null;
}
}
return;
}
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
// File storageDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
// File storageDir = new File(LoginActivity.getAppContext().getFilesDir() + "/NTA/temp");
if (!storageDir.exists()) {
storageDir.mkdir();
}
File imageFile = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
return imageFile;
}
