Amigo: A Java repository from chykidd

#Amigo Usage

Amigo is a hotfix library which can fix almost everything for your Android app.

How to use

Download

In your project's build.gradle

buildscript { 
    repositories {
        mavenCentral()
    }
    
    dependencies {
        classpath 'me.ele:amigo:0.5.0'
    }
}

In your module's build.gradle

apply plugin: 'me.ele.amigo'

android {
...
}

Customize loading page

Some time-consuming tasks are handled in a separate process to avoid ANR, you can customize the loading activity by add the follow code into your AndroidManifest.xml:

<meta-data
    android:name="amigo_layout"
    android:value="{your-layout-name}" />

<meta-data
    android:name="amigo_theme"
    android:value="{your-theme-name}" />

Make hotfix work

There are two ways to make hotfix work.

if you don't need hotfix work immediately

you just need to download new apk file to /data/data/{your pkg}/files/amigo/demo.apk, when app restarts next time, hotfix apk will be loaded as fresh as new.
```
 Amigo.workLater(context, patchApkFile);
```
work immediately, App will restart immediately
```
 Amigo.work(context, patchApkFile);
```

Remove patch

Amigo.clear(context);

note：All patch files would be deleted on the next start up.

Demo

And there is an Demo page in the app demonstrating how to apply patch apk. Run the task ./gradlew runHost preparePatch, and navigate to the demo page.

Development

Amigo gradle plugin

The plugin was put into buildSrc directory, which means the plugin code change will work immediately each time you build.

Amigo lib

The amigo plugin will select the right amigo lib automatically.

Run tests

There are two gradle tasks provided in the app/build.gradle, :app:runHost, :app:preparePatch, which can accelerate development.

./gradlew runHost, launch the host app
./gradlew preparePatch, build and push the patch apk to the device
apply the patch apk in the Demo page

Limits

have to change the way using a content provider

declare a new provider: the authorities string must start with "${youPackageName}.provider"

<provider
    android:name="me.ele.demo.provider.StudentProvider"
    android:authorities="${youPackageName}.provider.student" />

change the uri used to do the query, insert, delete operations:

// 1. inside your app process, no modifications need:
Cursor cursor = getContentResolver().query(Uri.parse("content://" + getPackageName() + ".provider.student?id=0"), null, null, null, null);
// 2. in another process, have to change the authorities uri like the following : 
Cursor cursor = getContentResolver().query(Uri.parse("content://" + targetPackageName + ".provider/student?id=0"), null, null, null, null);

Instant Run conflicts with Amigo, so disable Instant Run when used with amigo
RemoteViews's layout change in notification & widgetis not support
any resource id in here should be used with java RCompat.getHostIdentifier(Context context, int id)

Retrieve hotfix file
