How to confuse Code and related configurations with Android, and how to confuse code with android

How to confuse Code and related configurations with Android, and how to confuse code with android

Yesterday, the customer wanted to see to what extent the current project was developed, so he had to package the project signature into an apk. An error occurred while packaging the results. What was the problem. After the package is successfully completed, some functions are reported to be incorrect after installation. Sorry, we finally solved the problem. Record the errors and solutions.

1. How to confuse

Slave replaces it. The two configuration methods are the same, as long as they are introduced in the project. properties file. The former is to set the project. "# proguard. config =$ {sdk. dir}/tools/proguard/proguard-android.txt: proguard-project.txt '#' to remove it, the latter added a proguard. config = proguard. cfg.

 

2. How to prevent confusion of Third-Party jar packages

The obfuscation file I used is proguard. cfg.

The reason for the first package failure mentioned at the beginning is that a third-party jar package is introduced.

The reported error is as follows:

  1  Proguard returned with error code 1.

The solution is simple, that is, add the sentence-dontwarn in proguard. cfg.

The second operation reported an error. I used the real machine debugging to check the LogCat log output and found that the error was that the resource could not be found. The error was reported when a third-party jar was introduced, it turns out that the third-party jar package is also obfuscated when obfuscation is made, as long as the third-party jar package is not obfuscated.

The following is my final proguard. cfg configuration.

Now, OK
