App Crashes on launching specific activity - android-activity

My app crashes every time I try to launch the RegisterActivity. I have swapped out several other activities and the button launches them. Just not RegisterActivity. It is in the Manifest and there are no errors. I cannot figure out the problem. Any help will be greatly appreciated. Code follows:
// Link to Register Screen
btnLinkToRegister.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent(v.getContext(), RegisterActivity.class);
startActivityForResult(intent, 0);
The Activity that crashes the app:
package com.dip.allnavyinfo;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.TextView;
public class RegisterActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Set View to register.xml
setContentView(R.layout.register);
TextView loginScreen = (TextView) findViewById(R.id.link_to_login);
// Listening to Login Screen link
loginScreen.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
// Closing registration screen
// Switching to Login Screen/closing register screen
finish();
}
});
}
}

1- make sure that you have defined the activity RegisterActivity in your Manifest
2- change this :
Intent intent = new Intent(v.getContext(), RegisterActivity.class);
startActivityForResult(intent, 0);
into
Intent intent = new Intent(yourCurrentActivity.this, RegisterActivity.class);
startActivity(intent);

I had the same problem, I fixed it by sorting out my async tasks. I was making two calls in the same thread, once I separated them into two threads the problem was solved.

here is the code part :

final imgPicker.XFile? images =

try{
if (images != null) {
File? _cropped = await cropper.ImageCropper().cropImage(

if(_cropped != null) {
// cropped image code
}
} else {
showToast('Please select an image');
}
}
catch (e) {
log(e.toString());
}
whenever i select image from gallery after selection the app gets crashed, i tried removing the cropper part then it is working fine but when i user cropper my app get crashed.
here is the

I got the same error previously.
Just cross-check if you have added UCropActivity into your AndroidManifest.xml
<activity
android:name="com.yalantis.ucrop.UCropActivity"
android:screenOrientation="portrait"
android:theme="#style/Theme.AppCompat.Light.NoActionBar"/>
No configurations needed for iOS.
finally!! i have found the solution
go to android > app : right click on 'app' create a file name 'proguard-rules.pro'
add all of these following lines in the created file :
#Flutter Wrapper
-keep class io.flutter.app.** { *; }
-keep class io.flutter.plugin.** { *; }
-keep class io.flutter.util.** { *; }
-keep class io.flutter.view.** { *; }
-keep class io.flutter.** { *; }
-keep class io.flutter.plugins.** { *; }
-dontwarn org.xmlpull.v1.XmlPullParser
-dontwarn org.xmlpull.v1.XmlSerializer
-keep class org.xmlpull.v1.* {*;}
-keep class androidx.appcompat.** { *; }
now go to app/build.gradle and these lines inside the release block
signingConfig signingConfigs.debug
minifyEnabled true
useProguard true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
use flutter clean command, re-create the app in release mode and done!

Flutter [local_auth] Doesn't work on Android <28

I'm trying to work with local_auth, updating from 0.4.0 to 0.6.2
I followed the instructions, changing the FlutterActivity to FlutterFragmentActivity in my MainActivity.java
( according with this guide https://github.com/flutter/flutter/wiki/Upgrading-pre-1.12-Android-projects and with this thread https://github.com/flutter/flutter/issues/57678)
In this way
import io.flutter.embedding.android.FlutterFragmentActivity;
import io.flutter.plugins.GeneratedPluginRegistrant;
import io.flutter.embedding.engine.FlutterEngine;
public class MainActivity extends FlutterFragmentActivity {
#Override
public void configureFlutterEngine(FlutterEngine flutterEngine) {
GeneratedPluginRegistrant.registerWith(flutterEngine);
}
}
I also changed my style.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="LaunchTheme" parent="Theme.AppCompat.NoActionBar">
<item name="android:windowBackground">#drawable/launch_background</item>
</style>
</resources>
and my AndroidManifest.xml
<application
android:icon="#mipmap/ic_launcher"
android:allowBackup="false"
android:fullBackupContent="false"
android:label="XXX">
<activity
android:name=".MainActivity"
android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale|layoutDirection|fontScale|screenLayout|density"
android:hardwareAccelerated="true"
android:launchMode="singleTop"
android:theme="#style/LaunchTheme"
android:windowSoftInputMode="adjustResize">
<!-- This keeps the window background of the activity showing
until Flutter renders its first frame. It can be removed if
there is no splash screen (such as the default splash screen
defined in #style/LaunchTheme). -->
<meta-data
android:name="io.flutter.embedding.android.SplashScreenDrawable"
android:resource="#drawable/launch_background" />
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
<intent-filter>
<action android:name="FLUTTER_NOTIFICATION_CLICK"/>
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</activity>
<activity android:name="com.apptreesoftware.barcodescan.BarcodeScannerActivity"/>
<provider
android:name="vn.hunghd.flutterdownloader.DownloadedFileProvider"
android:authorities="${applicationId}.flutter_downloader.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/provider_paths"/>
</provider>
<meta-data
android:name="flutterEmbedding"
android:value="2" />
</application>
</manifest>
It works on Android 28 and higher, but not on older versions.

Android SearchView widget only works for Launcher Activity

I'm facing a very weird error right now. Basically, the app can search Google Places API using SearchView widget and show the results in Google Maps Android API V2, and the searchview widget is placed in action bar. I have referenced to this tutorial:
http://wptrafficanalyzer.in/blog/android-searchview-widget-with-google-places-api-using-actionbarsherlock-library/
The app works fine when the searchable activity (I name it as SearchPlace) is the main and launcher activity. However, if I try to intent to this activity from another activity, the app crash. I got NullPointerException caused by handleIntent().
I have attached a portion of the Manifest file below SearchPlace is the name of my searchable activity.

Can anyone help me plz ?
Thank you
Problem solved, modify the handleIntent() as
if(Intent.ACTION_SEARCH.equals(intent.getAction()))
{
String query = intent.getStringExtra(SearchManager.QUERY);
doSearch(query);
}
else if(Intent.ACTION_VIEW.equals(intent.getAction()))
{
getPlace(intent.getStringExtra(SearchManager.EXTRA_DATA_KEY));
}

caused by: java.lang.ClassNotFoundException

It is very frustrating that when running said app on a device or an emulator the "Unfortunately, app name has stopped" error came up. I believe that (by looking at the LogCat) I have pinpointed the problem to the error "java.lang.ClassNotFoundException". How I can fix this?
