I moved the initialization to different pages. On any page, the app wants to initialize it crashes.
I updated the flutter, any packages in my project, and Backendless to 7.2.3. And also tried any solution on the internet I could find.
I even made a balnc project with flutter just put backendless package and initialize it, then build apk and it crashes. Removed the initialization works.
Hello, @Ehsan_Nikaeen1.
Try to call initApp first, and only after that setUrl.
Best Regards, Nikita.
One moment. I will check
@Ehsan_Nikaeen1, I don’t have any problems.
You need to call setUrl if your app is on EU server. It just needs to be done after initApp.
Debug version is work as expected for you?
What version of backnedless_sdk are you using?
Yes, I was working fine all way and when I published it to google play I realized it crashes. It wasted two weeks of my time now, I delete every package from the app until getting to backendless. I use 7.2.3 version.
No difference!
No difference:
void initBackend() async {
await Backendless.initApp(
applicationId: Constants.APPLICATION_ID,
androidApiKey: Constants.ANDROID_API_KEY,
iosApiKey: Constants.IOS_API_KEY);
if ((await Backendless.isInitialized())!) {
Backendless.setUrl("https://eu-api.backendless.com");
}
}
I can assume that something is wrong with the gradle, manifest or proguard settings.
Right now we have a BackendlessViewer app on the public google play and appstore that uses the backendless_sdk. Here is it build.gradle settings:
def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
localPropertiesFile.withReader('UTF-8') { reader ->
localProperties.load(reader)
}
}
def keystoreProperties = new Properties()
def keystorePropertiesFile = rootProject.file('app/key.properties')
if (keystorePropertiesFile.exists()) {
keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
}
def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
throw GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}
def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
flutterVersionCode = '6'
}
def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
flutterVersionName = '1.2.0'
}
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'

Try redesigning your gradle to match the above as closely as possible.
My gradle file is like this: Standard one didn’t change anything.
def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
localPropertiesFile.withReader('UTF-8') { reader ->
localProperties.load(reader)
}
}
def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}
def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
flutterVersionCode = '1'
}
def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
flutterVersionName = '1.0'
}
apply plugin: 'com.android.application'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
def keystoreProperties = new Properties()
def keystorePropertiesFile = rootProject.file('key.properties')
if (keystorePropertiesFile.exists()) {
keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
}
android {
compileSdkVersion 30
compileOptions {

defaultConfig {

}
flutter {

}
signingConfig signingConfigs.release
minifyEnabled true
multiDexEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
add this to
buildTypes{
release{
}
}
Do I need to edit “proguard-android.txt”?
nope
also I don’t see proguard-rules.pro file in your
android -> app folder.
Not working.
I saw something in your previous tickets about editing proguard, Are you sure?
proguard-rules.pro should look like this:
#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.** { *; }
#Backendless
-dontwarn com.backendless.**
-dontwarn weborb.**
-keep class weborb.** {*;}
-keep class com.backendless.** {*;}
