</application>
Application intialization:
public class DemoApplication extends Application
{
@Override
public void onCreate() {
super.onCreate();
// the following line is important
Fresco.initialize(getApplicationContext());
}
}
// class variables
private static final int REQUEST_CODE = 123;
private ArrayList<String> mResults = new ArrayList<>();
// start multiple photos selector
Intent intent = new Intent(DemoActivity.this, ImagesSelectorActivity.class);
// max number of images to be selected
intent.putExtra(SelectorSettings.SELECTOR_MAX_IMAGE_NUMBER, 5);
// min size of image which will be shown; to filter tiny images (mainly icons)
intent.putExtra(SelectorSettings.SELECTOR_MIN_IMAGE_SIZE, 100000);
// show camera or not
intent.putExtra(SelectorSettings.SELECTOR_SHOW_CAMERA, true);
// pass current selected images as the initial value
intent.putStringArrayListExtra(SelectorSettings.SELECTOR_INITIAL_SELECTED_LIST, mResults);
// start the selector
startActivityForResult(intent, REQUEST_CODE);
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// get selected images from selector
if(requestCode == REQUEST_CODE) {
if(resultCode == RESULT_OK) {
mResults = data.getStringArrayListExtra(SelectorSettings.SELECTOR_RESULTS);
assert mResults != null;
// show results in textview
StringBuffer sb = new StringBuffer();
sb.append(String.format("Totally %d images selected:", mResults.size())).append("\n");
for(String result : mResults) {
sb.append(result).append("\n");
}
tvResults.setText(sb.toString());
}
}
super.onActivityResult(requestCode, resultCode, data);
}
Issue 1:
android.view.InflateException: Binary XML file line #7: Binary XML file line #7: Error inflating class com.facebook.drawee.view.SimpleDraweeView
Solution: make sure Fresco is initialized in app properly.
android:name=".DemoApplication"
...
Fresco.initialize(getApplicationContext());
Issue 2:
App crash while loading large amount of images
Solution: disable hardware acceleration for activity
<activity
android:name="com.zfdang.multiple_images_selector.ImagesSelectorActivity"
android:hardwareAccelerated="false"
android:configChanges="orientation|screenSize"/>
