android 版本号 5.1.1

先上结果:

1、luncher：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.test">
    <application
        android:sharedUserId="@android.uid.system"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.HOME" />
            </intent-filter>
        </activity>
    </application>

</manifest>

2、系统签名:

path:android-5.1.1_r1/out/host/linux-x86/framework/signapk.jar

path:android-5.1.1_r1/build/target/product/security/platform.x509.pem

path:android-5.1.1_r1/build/target/product/security/platform.pk8

将三个文件同生成的APK放在同一个文件夹内，在命令行执行

#java -jar signapk.jar platform.x509.pem platform.pk8 app-debug.apk Test.apk

java -jar signapk.jar platform.x509.pem platform.pk8 文件名.apk 目标名.apk

#adb install Test.apk

开机后会提示我们选择哪个home,我们要做的的就是在他弹出选择框时过滤出我们自己的,跳过点击步骤，直接将参数传递出去

3、修改源码

path: frameworks/base/core/java/com/android/internal/app/ResolverActivity.java

protected void onCreate(Bundle savedInstanceState, Intent intent,
        CharSequence title, int defaultTitleRes, Intent[] initialIntents,
        List<ResolveInfo> rList, boolean alwaysUseOption) {
    setTheme(R.style.Theme_DeviceDefault_Resolver);
    super.onCreate(savedInstanceState);
    中间是查找home和配置列表，配置好列表后选择我们自己的home,然后调用原有的start
    //函数最后增加
    for(int i=0;i<mAdapter.mList.size();i++){
            ResolveInfo info= mAdapter.mList.get(i).ri;
            if(info.activityInfo.name.equals("com.example.test.MainActivity")){
                startSelected(i, true,false);
                return;
             }
        }
}

修改完成，模块编译，运行

android-5.1.1_r1/frameworks/base/core# mm
