私は OpenFileChooser を使用していますが、Android 4.2.2(Jelly Bean) で動作していますが、Android Lollipop (5.0) バージョンでは動作していません。4.0 から新しいバージョンまでサポートするこのことを行うオプションはありますか?
このチュートリアルを使用しています
そして、それに関して提出された問題があります
問題 62220: Android 4.4 WebView で がクリックされたときに openFileChooser が呼び出されない
ファイルチューザー/画像チューザーを含むWebページを呼び出したwebviewを使用しています。
Add this before onCreate:
private WebView mWebView;
private ProgressBar mProgressBar;
//new block
private static final String TAG = MainActivity.class.getSimpleName();
public static final int INPUT_FILE_REQUEST_CODE = 1;
public static final String EXTRA_FROM_NOTIFICATION = "EXTRA_FROM_NOTIFICATION";
private ValueCallback<Uri[]> mFilePathCallback;
private String mCameraPhotoPath;
// Storage Permissions
private static final int REQUEST_EXTERNAL_STORAGE = 1;
private static String[] PERMISSIONS_STORAGE = {
Manifest.permission.READ_EXTERNAL_STORAGE,
Manifest.permission.WRITE_EXTERNAL_STORAGE,
Manifest.permission.CAMERA
};
Add to mWebView.setWebChromeClient(new WebChromeClient() { this:
public boolean onShowFileChooser(WebView webView, ValueCallback<Uri[]> filePathCallback,
WebChromeClient.FileChooserParams fileChooserParams) {
//verifyStoragePermissions(MainActivity.this);
Log.e("111","onShowFileChooser");
if(mFilePathCallback != null) {
mFilePathCallback.onReceiveValue(null);
}
mFilePathCallback = filePathCallback;
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(MainActivity.this.getPackageManager()) != null) {
// Create the File where the photo should go
File photoFile = null;
try {
photoFile = createImageFile();
takePictureIntent.putExtra("PhotoPath", mCameraPhotoPath);
} catch (IOException ex) {
// Error occurred while creating the File
Log.e(TAG, "Unable to create Image File", ex);
}
// Continue only if the File was successfully created
if (photoFile != null) {
mCameraPhotoPath = "file:" + photoFile.getAbsolutePath();
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(photoFile));
} else {
takePictureIntent = null;
}
}
Intent contentSelectionIntent = new Intent(Intent.ACTION_GET_CONTENT);
contentSelectionIntent.addCategory(Intent.CATEGORY_OPENABLE);
contentSelectionIntent.setType("image/*");
Intent[] intentArray;
if(takePictureIntent != null) {
intentArray = new Intent[]{takePictureIntent};
} else {
intentArray = new Intent[0];
}
Intent chooserIntent = new Intent(Intent.ACTION_CHOOSER);
chooserIntent.putExtra(Intent.EXTRA_INTENT, contentSelectionIntent);
chooserIntent.putExtra(Intent.EXTRA_TITLE, "Image Chooser");
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, intentArray);
startActivityForResult(chooserIntent, INPUT_FILE_REQUEST_CODE);
return true;
}
And add this to 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) {
System.out.println("In KitKat Condition");
if (requestCode != FILECHOOSER_RESULTCODE || mUploadMessage == null) {
System.out.println("In != Null");
super.onActivityResult(requestCode, resultCode, data);
return;
}
if (requestCode == FILECHOOSER_RESULTCODE) {
System.out.println("requestCode == FileChooser ResultCode");
if (null == this.mUploadMessage) {
System.out.println("In null == this.mUploadMessage");
return;
}
Uri result = null;
try {
if (resultCode != RESULT_OK) {
result = null;
} else {
//newcode
// retrieve from the private variable if the intent is null
result = data == null ? mCapturedImageURI : data.getData();
KitkatPath = Uri.parse("file://"+getPath(MainActivity.this, result));
System.out.println("KitkatPath== "+KitkatPath);
System.out.println("result = "+result);
}
} catch (Exception e) {
// Toast.makeText(getApplicationContext(), "activity :" + e, Toast.LENGTH_LONG).show();
e.printStackTrace();
}
// mUploadMessage.onReceiveValue(result);
mUploadMessage.onReceiveValue(KitkatPath);
System.out.println("mUploadMessage = "+mUploadMessage);
mUploadMessage = null;
}
}
}
Last thing, add to Manifest
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.CAMERA"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
It should work on lollipop and marshmallow
問題 62220で説明されているように: Android 4.4 webview で がクリックされたときに openFileChooser が呼び出されない:
openFileChooser公開 API ではありません。
API 21 (Android 5.0 Lollipop) 以降では、 を使用する必要がありますonShowFileChooser。
API 19 (4.4) では、要素をカスタム DOM+JavaScript@JavascriptInterfaceに置き換えるスクリプトを使用したり、挿入したりすることで回避できます。<input type="file">参照: https://codemumbai.wordpress.com/android-webview-image-upload-solved/
