I am installing apk file in android emulator. But when I gave the command ADB INSTALL CALENDAR.APK in command prompt it is displaying the error as Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES]. What would be the reason? Can anybody help me regarding this?
Thank you,
All Android packages must be signed to be installed, well at least since version 1.6.
So that particular package is presumably older. You can get a newer one (or recompile yourself if you have the sources), or use an older version in your emulator (1.5).

After a recent flutter update, my app stopped working. Throws out from the mobile application. Can you help me? I have got this error:
adb: failed to install /Users/User/Desktop/project/build/app/outputs/flutter-apk/app.apk: Failure[INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package com.package.name: signatures do not match previously installed version; ignoring!]
Before that everything worked. I don't know what to do, please help. The command adb uninstall <package_name> won't help. The project is already on Google Play
I tried reinstalling. Install the original version of the mobile application. update all dependencies, but nothing helped
that's because it's different from the previous version you can see in a similar case here
I'm using Mac mini , MacOs monterey and m1 chip. When trying to setup flutter, it is giving error.
command: flutter doctor
o/p: /Users/admin/Desktop/flutter/bin/internal/shared.sh: line 229: /Users/admin/Desktop/flutter/bin/cache/dart-sdk/bin/dart: Bad CPU type in executable
I have tried below command but it is also not working,
Terminal command: sudo softwareupdate --install-rosetta --agree-to-license
Terminal output:
By using the agreetolicense option, you are agreeing that you have run this tool with the license only option and have read and agreed to the terms.
If you do not agree, press CTRL-C and cancel this process immediately.
Rosetta 2 update is not available
you have to install rosetta first. In your terminal type:
/usr/sbin/softwareupdate --install-rosetta --agree-to-license
I got this error on MacOs VMware
and finaly I realized that i was downloaded the flutter sdk for arm Architecture, but i need this for x64 (intel) Architecture.
run "softwareupdate --install-rosetta" in the terminal
On macOs accidentally I downloaded arm architecture than x64 version.
Download proper version as per the system requirements.
My mistake was that , I had installed flutter sdk before installing the Rosetta. So that's why it was giving the above error. So, to resolve this, I removed the flutter sdk and installed rosetta first then again installed flutter and it worked properly.
Where can I see the flutter version used in a flutter project? Is there a file inside the project directory where I can see it? I think it is not specified inside the pubscpec.yaml file
So far, I think the specific version can not be found but only what versions can be used in a project. It can be found at the bottom part of pubscpec.lock file

It will not show version project wise. It will overall flutter version that you have installed in your system. For that:
Open your flutter project root directory in Command Prompt or Terminal type:
flutter --version command.
After typing the above command hit enter and You’ll see it will display us the currently installed flutter and Dart version in your computer and also tells us which version type we have installed like Stable or Beta.
Note: There is no such feature/command to check about which version of flutter you have used in Specific project.
Check this thread it will give you more idea:
https://github.com/flutter/flutter/issues/14230
All projects you run will use the flutter sdk installed in your machine/computer from where you specified its location from. So if the version the project uses don't match with the version you've and they conflict, you will have errors and if there is a huge gap and breaking changes, you'll need to either upgrade or downgrade the sdk. But most of the time, things are deprecated before they just become breaking changes and so you shouldn't have big issues. So the best thing to do is usually to upgrade. First check your sdk version via flutter --version. If its outdated, use flutter upgrade to upgrade it.
You can either run flutter --version to check flutter version installed on your machine or check it in your pubspec.lock file for current flutter version in your project
sdks:
dart: ">=2.10.0-110 <2.11.0"
flutter: ">=1.16.0 <2.0.0"
So I tried implementing Facebook Login and followed all the steps accordingly. After having errors with FBSDKcorekit/FBSDKcorekit.h' file not found, I decided to pivot over to working on other components.
Lo' and behold, I have this error giving me trouble now. I followed along with this video: https://www.youtube.com/watch?v=rAXVKapP5cM&t=458s where I used the react-native install react-native-fbsdk and react-native link react-native-fbsdk commands in my terminal.
If it helps, I'm getting the following compile error in my terminal:
The following build commands failed:
CompileC /Users/someUser/desiredProject/ios/build/Build/Intermediates/RCTFBSDK.build/Debug-iphonesimulator/RCTFBSDK.build/Objects-normal/x86_64/RCTFBSDKGraphRequestManager.o RCTFBSDK/core/RCTFBSDKGraphRequestManager.m normal x86_64 objective-c com.apple.compilers.llvm.clang.1_0.compiler
(1 failure)
I'm not sure if it was the tinkering around with the react-native-fbsdk or making links to it that caused this error. Note my project was working before I was trying to implement Facebook Login and using the link command.
What's going on here?
Thanks in advance for your time and patience.
edit: Also I did not implement any of the Facebook login code yet since I couldn't get a successful build on Xcode.
#kdizzle Make sure you have the right packager running in the terminal, sometimes you may have a packager associated with another react native project running, this happens because when you stop running an xcode RN project, it doesn't stop the packager in the terminal, and when you start/open another RN project in xcode, it simply checks if a packager is running, doesn't check if it's associated with the current project. So make sure you stop all of the packager instances in the terminal and then open the RN project again.
This may happen when upgrading a project to a newer version of react-native. To fix it,
Stop your packager.
Quit your iOS/android simulator.
Reinstall your modules: rm -rf node_modules && npm install
Restart your packager and simulator, e.g. react-native run-ios
I had this issue and it happened when I changed Hardware within the simulator. To fix it I had to kill the packager and run 'react-native run-ios' again. It didn't happen all the time but when it did this fixed it for me!
Another use is in a Brownfield App. Check your iOS and/or Android react-native versions. If they don't match exactly you will see this error screen too.
For example: I had a react native instance running 0.45.1 while Android had 0.45.0 installed. The solution for me was to make sure everything was running the same version.
None of the above answers have worked for me, so I researched the 'react-native' options a little and ended up:
Deleting the iOS and android folders from the app directory altogether
Running 'react-native eject'
Re-running 'react-native run-ios'
After that the iPhone emulator seemed to have no problem with the app.
This problem would appear when React Native libraries in ios project can not found.
I happend to meet this problem when i update my react-native version from 0.42 to 0.44, and cause that a file named RCTConvert+Map disappear in 0.44, so i update my pod.
command: pod update
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.
