# AndFix
[ ](https://bintray.com/supern/maven/andfix/_latestVersion)
[](https://travis-ci.org/alibaba/AndFix)

AndFix is a solution to fix the bugs online instead of redistributing Android App. It is distributed as [Android Library](https://sites.google.com/a/android.com/tools/tech-docs/new-build-system/aar-format).
Andfix is an acronym for "**And**roid hot-**fix**".
AndFix supports Android version from 2.3 to 7.0, both ARM and X86 architecture, both Dalvik and ART runtime, both 32bit and 64bit.
The compressed file format of AndFix's patch is **.apatch**. It is dispatched from your own server to client to fix your App's bugs.
## Principle
The implementation principle of AndFix is method body's replacing,
### Method replacing
AndFix judges the methods should be replaced by java custom annotation and replaces it by hooking it. AndFix has a native method `art_replaceMethod` in ART or `dalvik_replaceMethod` in Dalvik.
For more details, [here](https://github.com/alibaba/AndFix/tree/master/jni).
## Fix Process
## Integration
### How to get?
Directly add AndFix aar to your project as compile libraries.
For your maven dependency,
```xml
com.alipay.euler
andfix
0.5.0
aar
```
For your gradle dependency,
```groovy
dependencies {
compile 'com.alipay.euler:andfix:0.5.0@aar'
}
```
### How to use?
1. Initialize PatchManager,
```java
patchManager = new PatchManager(context);
patchManager.init(appversion);//current version
```
2. Load patch,
```java
patchManager.loadPatch();
```
You should load patch as early as possible, generally, in the initialization phase of your application(such as `Application.onCreate()`).
3. Add patch,
```java
patchManager.addPatch(path);//path of the patch file that was downloaded
```
When a new patch file has been downloaded, it will become effective immediately by `addPatch`.
## Developer Tool
AndFix provides a patch-making tool called **apkpatch**.
### How to get?
The `apkpatch` tool can be found [here](https://github.com/alibaba/AndFix/raw/master/tools/apkpatch-1.0.3.zip).
### How to use?
* Prepare two android packages, one is the online package, the other one is the package after you fix bugs by coding.
* Generate `.apatch` file by providing the two package,
```
usage: apkpatch -f -t -o -k -p <***> -a -e <***>
-a,--alias keystore entry alias.
-e,--epassword <***> keystore entry password.
-f,--from new Apk file path.
-k,--keystore keystore path.
-n,--name patch name.
-o,--out output dir.
-p,--kpassword <***> keystore password.
-t,--to old Apk file path.
```
Now you get the application savior, the patch file. Then you need to dispatch it to your client in some way, push or pull.
Sometimes, your team members may fix each other's bugs, and generate not only one `.apatch`. For this situation, you can
merge `.apatch` files using this tool,
```
usage: apkpatch -m -o -k -p <***> -a -e <***>
-a,--alias keystore entry alias.
-e,--epassword <***> keystore entry password.
-k,--keystore keystore path.
-m,--merge path of .apatch files.
-n,--name patch name.
-o,--out output dir.
-p,--kpassword <***> keystore password.
```
## Running sample
1. Import samplesI/AndFixDemo to your IDE, append AndFixDemo dependencies with AndFix(library project or aar).
2. Build project, save the package as 1.apk, and then install on device/emulator.
3. Modify com.euler.test.A, references com.euler.test.Fix.
4. Build project, save the package as 2.apk.
5. Use apkpatch tool to make a patch.
6. Rename the patch file to out.apatch, and then copy it to sdcard.
7. Run 1.apk and view log.
## Notice
### ProGuard
If you enable ProGuard, you must save the mapping.txt, so your new version's build can use it with ["-applymapping"](http://proguard.sourceforge.net/manual/usage.html#applymapping).
And it is necessary to keep classes as follow,
* Native method
com.alipay.euler.andfix.AndFix
* Annotation
com.alipay.euler.andfix.annotation.MethodReplace
To ensure that these classes can be found after running an obfuscation and static analysis tool like ProGuard, add the configuration below to your ProGuard configuration file.
```
-keep class * extends java.lang.annotation.Annotation
-keepclasseswithmembernames class * {
native ;
}
```
### Self-Modifying Code
If you use it, such as *Bangcle*. To generate patch file, you'd better to use raw apk.
### Security
The following is important but out of AndFix's range.
- verify the signature of patch file
- verify the fingerprint of optimize file
