I'm new to flutter and on a phone I have it works and the app runs fine, but I sent the apk to another device and it couldn't be installed, I don't know if it's because of a plugin I'm using that is "speech to speech", since in that plugin I changed the version of min sdk to 21 but the android that I try to install has an android version of 10 that is higher, it seems to me, what would be the cause?
Remember Android no longer accept the app which has not been signed as release,. make sure you are making you are signing the app correctly, Android studio will help you.
The build flavor should be release, and the signature must be created before. But the easiest way is to run the app in profile mode,
flutter run --profile
Profile mode run as release mode but doesn't require to be manually signed.
There could be other reasons but do you know that the Flutter app cannot be installed on x86 Android
Flutter does not currently support building for x86 Android

I am using flutter build apk to build apk. Now the apk is not installing on our android device. it was showing like App not installed as shown image.
What may be the issue and how can I solve this?
Verify that you can install 3rd party apps in settings and make sure you have enough space available.
I have created a web app using Flutter and it is running fine.
I wanted to create a mobile app out of it with as little modification to the code as possible and wanted to run it in an Android Emulator, so I installed Android Studio and then a device in ADV Manager. The code did not show any errors but Android Studio is not able to locate the newly installed device. Am I missing something?
The question could also be reframed as: how to convert a Flutter web app into a mobile app.
Source of this answer is :here
Can you try to run the below command in terminal:
flutter devices
Does it show something like this?
Android SDK built for x86 (mobile)
If not, then try to run the following commands:
flutter config --android-sdk <path to android sdk>
flutter config --android-studio-dir <path to android studio>
Replace with the actual path to the SDK in your machine.
And then restart your Android Studio. You should see your virtual device listed under Flutter Device Selection.
Please note, to find the path to Android SDK, you can go to Preferences as shown in this image
Am not able to install the APK in my mobile generated by gradle. it's working fine on an emulator but when I try to install on my mobile its starts installing and in the middle, it gives the error APK not installed. Am running android 10. Paths from where I picked the debug APKs are as follow.
<project>/build/app/outputs/apk/debug/app-debug.apk
<project>/build/app/outputs/apk/debug/app.apk
<project>/build/app/outputs/flutter-apk/app-debug.apk
It seems your apk does not have certificate yet.
you cant install it just like that. you can either certify it build release android app
or set your phone to install app form unknown source. in app settings or security settings
If you're trying to manually install the app-debug.apk, you should rather consider generating app-release.apk but if you can't debug the app, then you might considering opening up your developer options.
I am totally new to Cordova, but now I have installed Cordova with NPM and installed Android SDK and set up an AVD which seems to work perfectly, until I want to emulate my project. Where the actual app for some reason is not loaded into the emulator.
The following action is done:
marvin:HelloWorld$ cordova -d emulate android
cordova library for "android" already exists. No need to download. Continuing.
Wrote out Android application name to "HelloWorld"
Wrote out Android package name to "com.example.hello"
Calling plugman.prepare for platform "android"
Preparing android project...
Processing configuration changes for plugins.
Iterating over installed plugins: []
Writing out cordova_plugins.js...
Running on emulator for platform "android" via command ""/home/marvin/Development/projects/HelloWorld/platforms/android/cordova/run" --emulator" (output to follow)...
Then it start Android emulator up, but the app is not there. Does anybody have a suggestion to fix this issue, so I am capable of actually testing in my emulator?
Thank you in advance.
I just had the same problem, and I was missing PATH to platform-tools in android sdk folder, after I added it everything was in place.
I had the same problem as well; I could run the cordova emulate android command just fine, and the emulator would eventually start up and function, however, the test app was never installed on the device. I was not getting any errors from the Cordova CLI or the console or anything.
I found that there is a bug report about this issue here: https://issues.apache.org/jira/browse/CB-4285
Two solutions have been found for this issue:
1. Make sure you are using an Oracle JDK and not an IBM JDK, and
2. Make sure the AVD that emulate starts up has a min-target-sdk set to API 10 (Android 2.3.3) or higher. (This was my problem.)
Sometimes it works deleting the previously installed version of the app in the emulator. For this you could also launch it with the option "Wipe user data" checked.
Just for the record, none of the other solutions worked for me.
I had the same issue. Following solved it for me.
Make sure that API level of your AVD is greater than minSdkVersion specified in config.xml specified in your cordova app.
If anyone still having this issue:
I had a same problem with device being offline.
if ddms is running it looks after connected devices.
adb kill server
and than run ddms
Also make sure your app id doesn't begin with a number or any other character like "_". For example, if your app id is com.4company.MyApp or com._company.MyApp it just won't load on the emulator. The first one is because Java doesn't allow names beginning with a number, and the second one I guess it's a Cordova thing.
You should also use adb logcat to show the emulator errors on the command line.
For me, the app was not starting up because I had a second emulator running in the background. Uninstalling bluestacks (android emulator for windows) fixed the issue in my case. Running "adb logcat" should tell you if you have multiple emulators running.
I just had the same problem, and It was my emulator device that was with the API 15. Just updated to API 17 and the problem solved.
I started developing with Titanium and now I really stuck on one part.
I downloaded the Adroid SDK and added the path to Titanium:
/Users/michael/Downloads/android-sdk-mac_86/
I can open e.g. Kitchen Sink in the iPhone Simulator without problems, but when I want to open it in Android then my screen looks like this: Screenshot
Why is down there all the time, even after 2 hours of waiting, the label "loading..." ?
some great advice given here - helped me out.
Switching to TRACE will probably show that Android SDK Platform 1.6 and API 4 is missing.
More info here
1) You can install Android SDK 1.6 (run tools/android from your Android SDK folder and download the older SDK 1.6 from the Google Repository),
and Titanium will detect Android SDK
2) As for Android SDK 2.2, adb moved to platform-tools folder, so you will have to create a link in [your-android-sdk-folder]/tools e.g. :
ln -s ../platform-tools/adb
(full instructions for non-linux here : http://guides.appcelerator.com/en/getting_started.html)
Finally, in the Titanium Test&Package/Run emulator window, you will have the choice between Android SDK 1.6 and 2.2
Try to open your Android_SDK_Dir/tools, run file android to create a new Android Virtual Device. After that, open your Titanium again. Maybe this will solve your issue.
Take a look at your image. Value of SDK listbox is "...loading...". This means you Titanium cannot determine which Android Virtual Device is. So, as I said, try to create new Android Virtual Device first.
having the same issue - have you found a workaround?
found out that after downloading the android sdk - there are other components to be downloaded, which is different from previous versions. Also found some implication that loading the android emulator prior to launching the app from titanium may yield better results.
check the android docs for updating the sdk via the avd manager
load the emulator first video:

Try setting the Filter from "Info" to "Trace" that may illuminate things.
Most commonly, you may not have the right platforms installed. Just install all of them if that's the case.
add a blank folder android-7 in android/platforms ..n restart titanium ..it worked for me on ubuntu
