I have cloned from github and made some changes in K-9 Mail application. I was able to succeffully build a signed apk, but I can't test it on my device, because the installation is blocked by Play Protect. How can I deal with it? How can I test changes that I have made?
what software did you use to compile the apk? If you used Android Studio or Eclipse you should be able to use an emulator to test your apk file.

I developed this react Native mobile application called "ClkApp". I Published my application using expo and I can see the application on my phone.
Now, I want to publish this application on Google play. I completed all the required steps including paid the fee of 25 dollars. One of the step requires that I generate a signed APK. I saw some tutorials how to generate the Signed APK and all of them build the application using android studio and go to Build -> Generate Signed APK. I tried to open my app on Android studio, but I don't see any option under Build menu other than "Analyze APK" and "deploy Module to app engine". there is another option called "make", but that is disabled. Below is the image:
I created a new test application using android studio and I can see the options like generate signed APK, Build etc. for this test application. I don't want to create "ClkApp", my original app", application using android studio because that will take lot of time. Is their any way, I can generate the APK on this existing application and don't have to use android studio at all.
Any help will be greatly appreciated.
Since you have build your app with Expo. You can use Expo to generate apk (standalone app)
After you configure app.json and run expo build:android
Check this for details https://docs.expo.io/versions/v32.0.0/distribution/building-standalone-apps/
I made an Android app using Android studio, deployed and ran it directly by using my mobile running Oreo.
It installed successfully. But later I tired to share the APK from my mobile to other mobiles. But none of them are able to Install it.
However, if I build the APK and share the app-debug.apk to other mobiles. It Installs successfully.
I can't build APK and share app-debug.apk it everyone.
I usually deploy it in my mobile, share APK(which used to work before)
Can anyone please help
Please excuse typos, I have typed from mobile.
There might be a signing issue. Is your app signed? The default signing is the debug signing. When you just build and deploy or run it on a connected device, it is signed by default as a debug sign.
If it is not uniquely signed, then running or installing on other devices might not be possible. Look at the app signing instruction and guide by Google, here, if you wish to distribute your app on other devices.
Another problem might be in the security authorization of other devices. Your device on which you are building has the developer options turned on. To run and install unsigned apps you'll need to activate the developer options in the device you want to run it on. Look at this link about Developer Options and how to turn it on.
by default the Android Studio packages just the needed files and installs the app in your mobile. If you share to other mobiles, the app will not install in few devices due to a few reasons like OS version, files mismatch, SHA keys mismatch, etc.
However, if you build the APK and share, the APK is equipped to be installed in any device starting from the minimum SDK version to the target SDK version.
I am new to react-native app development. I wanted to know how can a developed app be shared between other developers without having a local dependency. Is an apple developer account needed for a test build to be shared in ios as well? How can the test build be created?. I wanted the build to be created and downloaded on any ios device or android for testing purpose and without having depending any of the local code changes.So the build downloaded should not get updated after any code change done after that.
Is there an easy way to do it?
To share a release build for Android please follow this guide Generating Signed APK.
But for iOS you gonna need a Apple Developer account, I don't know the whole process exactly.
I do understand that a .apk file is created in the bin folder of an android project, when the project is run.
I have a question about this: is it possible that there would be any difference in the functionality of an app installed via eclipse (as in connecting the phone to the computer and uploading and installing the app on the phone) versus installing the app by downloading a .apk placed on a secure server?
The reason I ask this question is that I usually put up the .apk file on a secure server and the testing team downloads and installs the app for testing purposes. The testing team has started to report app crashes when accessing this app. However, I don't seem to be seeing the any such problems (even while replicating the same scenarios) with the app when I install it on the phone via a cable connected to the computer.
You might be falling into a caching issue. Make sure you get the QA team a new filename of the apk on the server to ensure that they never get a cached apk when downloading it. Also maybe create a md5 sum of the apk locally and run md5 on the apk on the server after upload to ensure it is the same.
e.g. use
md5 yourapk.apk > yourapk.md5
on your machine and the server..
Most likely you QA team has found issues that are specific to the device or Android platform version they test with. Try with your apk with the same hardware in your dev environment.
I don't see how that would possible. The Eclipse ADT plugin just calls the executables in the specified Android SDK location on your hard drive and the .apk gets generated only once when you use Eclipse to install the application to your plugged phone.
Unless you're packaging the two versions in a different way, that shouldn't be possible. My guess is that your testing team has just found bugs specific to the runtime environment (the phone). Maybe a different version of Android, conflicting custom ROM, etc.
No, there is no difference , if the apk on the secure server is as latest as you have on your computer.
I would recommend you to clean your project before uploading the apk to the server.
Regarding the crashes, i guess there are some location based problems.
Also check if you are uploading the apk from your workspace. or some other older version which is located in different place that you are not using anymore.
I am starting to explore the game development using unity 3d for android. I have downloaded the trial version of unity 3.3. I went through few tutorials.
I have one question that is not answered. In the normal apps which we develop using eclipse, we can deploy onto mobile by copying the apk file. What about unity 3d? How do I get the game onto my phone. I don't want to publish on market.
It is possible to transfer your assets to Eclipse. When it's integrated you can debug via your android phone. Be sure to read the tutorial on Unity's homepage. There is a step by step start-up guide and some more. Following links are worth looking at:
Getting started with Unity and Android
Official - Integrating Unity with Eclipse
Alternative link - Integrating Unity with Eclipse
It would seem that the official "integration" link is broken so I updated with a forum post that covers the same topic. However I recommend to try with the official link first.
Yes, you can simply copy the apk to your device and install it. Unity builds an apk file (and will optionally sign it using a keystore that you provide or let it generate for you). Once it has built that apk you can deploy it normally. You can even have it include a customized manifest in the apk that it builds if you want to (but it generates a nice one from your settings in the unity project by default).
There are two methods for this, as far i understand,
Using Build Settings--> Build, It builds the apk file that can be installed on your device using adb install <apk file path and name>
Using Build Settigs--> Build and Run. Which automatically installs the apk built apk file on your device if connected
go to file
-build
-select android platform(your pc has to have android development kit)
-save your apk
As it is still unanswered I try to close this question
First of all, current version of Unity 5.2 is much more powerfull than version 3.3. mentioned in original question.
What about unity 3d? How do I get the game onto my phone. I don't want to publish on market.
The same way. Unity allows you to publish build as *.apk on ocal machine and then you can just copy it to your phone and install it.
What is more cool, now you can debug your application running on phone. You have to install Unity Remote to the phone and run. Now you can set breakpoints and debug as normally.
If you change your mind and go to publish on Market - Unity will sign your *.apk
Hope this helps someone, good luck!
The Same way you generate the apk through Eclipse like that in unity you need to build the project. For that android sdk and jdk should be installed in your system and u need to show those path in the unity Preferences then u need a google keystore and need to sign in with that key store in the Publisher settings and then u are able to build the apk which will be store in your local system and you can copy that to your mobile and install the apk file.
