Let’s get into the full review of the Signed vs Unsigned apk. Every time you create an Android project, a few different APKs will be generated by default. These include versions for use in development and testing as well as production.
The development and release versions are identical in many respects, such as binaries, resources, and manifest files. Still, the release APK can be signed with your certificate and optimized using the Zipalign tool for better performance.
However, there are some extra files in the signed version that indicate it has been signed. The signed and unsigned APKs are precisely the same. Unsigned APK files can be used to generate signed APK files simply by running the JDK Jarsigner tool on them. This produces a new APK file that includes several new files inside the META-INF folder.
Installing an unsigned APK is impossible on Android devices. You don’t have to be confused with the Unknown sources option in Settings -> Security, which should be checked to ensure that the unsigned APK cannot be installed. Just delete the three files from a standard APK file with zip tools, and you’ll see that it won’t install.
So now, let’s get it more clarified and explained…
Difference between Signed and Unsigned Android mod APK.
Because an Android APK is simply a zip file, the only way to tell the difference between a signed and an unsigned APK created from Eclipse is to unzip the files and compare the contents of the two files. There should be only one significant difference: The signed APK will contain an additional folder named “META-INF,” which will include three files, which are as follows: Here’s the entry for the Android project manifest:
1) MANIFEST.MF – This file contains a list of all of the files in the archive, as well as a base64encoded SHA1 hash of their contents; for example, here’s the entry for the Android project manifest: Name: AndroidManifest.xml SHA1-Digest: 2/Ek5ZsQE2qFvLZt2x4srQSSd7A=
2) CERT. SF-This file is very similar to the MANIFEST.MF file, with the exception that it does not give the SHA1 hash of the contents for a file; instead, it lists a hash of the lines for a file from the MANIFEST.MF file.
For example, here is the entry for the Android project manifest:
Name: AndroidManifest.xml SHA1-Digest: 6ycpIZPMu943qFF8EDpPun7j4UQ=
where it is, “6ycpIZPMu943qFF8EDpPun7j4UQ=“ is the SHA1 hash of this main string from MANIFEST.MF”
Name: AndroidManifest.xml SHA1-Digest: 2/Ek5ZsQE2qFvLZt2x4srQSSd7A= “*It should be noted that the blank line following the digest line is taken into consideration while calculating the SHA1 hash.
03. CERT.RSA Certificate of signing authority (CERT.RSA): This file contains both the signature of the CERT.SF file as well as the certificate that was used for signing. The only thing that has to be done in order to “unsign” an APK file is to remove the META-INF directory from the APK file itself, which can be accomplished using zip tools.
Signed vs Unsigned APK; How to Generate Signed APK in Android Studio.
If you don’t specify a signingConfig at all in the release build type, your build will not be protected by a signature. Release builds do not inherit the default signing configuration used by debug builds, so it should also work for them.
So how to Generate Signed APK in Android Studio? You’ll need to navigate to the Gradle tasks window and select the assembleRelease task; standard builds via “Make Project” do not result in the creation of the final APK; instead, you’ll need to use the assembleRelease job. Actually, you may create an unsigned.APK file simply by constructing it as follows:
- The Build Variants menu may be seen on the left-hand side of the Android Studio window, which is where it will be generated (maybe written vertically). Simply click on it.
- The Build Variants window tab has now displayed; select debug and then release to make the changes.
- Rebuild your project application by selecting build> Rebuild Project from the menu bar.
- Then click Run, a new window will appear. Click Run > Continue anyhow > and then click Finish. Select the device that you need to use to launch the program > OK.
- Even though the application will not function on your device, a release build version of your.apk will be developed and placed in the same directory as your debug versions: C:\ANDROID PROJECT DIRECTORY\app\build\outputs\apk\
- You’ll notice that the file’s name is app-release-unsigned.apk, which is exactly what we were looking for.
