一. 條件

系統簽名

須要放到 /system/app裏做爲系統app

二. 適用環境

機頂盒開發，系統開發，車機開發，智能設備開發。

三. 步驟

1. 在 AndroidManifest.xml 中

1.1. 在清單文件 AndroidManifest.xml 添加 android.uid.system 聲明爲系統應用。
1.2. 權限java

<uses-permission android:name="android.permission.INSTALL_PACKAGES" />
 <uses-permission android:name="android.permission.DELETE_PACKAGES" />
 <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />
 再添加讀寫權限這個能夠實現安裝時讀取路徑
 <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />複製代碼

1.3 總配置步驟圖
android

2. 代碼部分 (兩種方法均可以實現，如今項目選擇了第二種)

方法一

以前公司開發時機器是api 17 ，獲取了系統裏pm的代碼經過aidl實現加反射實現這個方法也是比較正規的作法
去大家系統的源碼裏找到android.content.pm把裏面的代碼拷拷出來看圖這幾個就夠了。

代碼段api

安裝
public void installApp(final String path, final String packageNames){
 File apkFile = new File(path);
    /* 當前app沒法訪問外置sd卡文件，exists()會爲false因此直接拋異常最好 if(!apkFile.exists()){ sendBroadcastMsg(packageNames,false,"路徑錯誤"); return; }*/
    try {
        Class<?> clazz = Class.forName("android.os.ServiceManager");
        Method method_getService = clazz.getMethod("getService", String.class);
       IBinder bind = (IBinder) method_getService.invoke(null, "package");
        IPackageManager iPm = IPackageManager.Stub.asInterface(bind);
        iPm.installPackage(Uri.fromFile(apkFile), new IPackageInstallObserver.Stub(){
            @Override
            public void packageInstalled(String packageName, int returnCode) throws RemoteException {

            }
        }, 2, apkFile.getName());
    } catch (Exception e) {
        sendBroadcastMsg(packageNames,false,"安裝異常");
        e.printStackTrace();
    }
}
卸載
public void uninstallApp(String packageName){
    try {
        Class<?> clazz = Class.forName("android.os.ServiceManager");
        Method method_getService = clazz.getMethod("getService",String.class);
        IBinder bind = (IBinder) method_getService.invoke(null, "package");
        IPackageManager iPm = IPackageManager.Stub.asInterface(bind);
        iPm.deletePackageAsUser(packageName,null,0,2);
        System.out.println("=================>>卸載成功");
    } catch (Exception e) {
        e.printStackTrace();
        System.out.println("=================>>卸載失敗");
    }
}複製代碼

方法二 (兼容到6.0，6.0以上沒測過，如今用的是這種沒一點問題兼容公司因此係統，無需AIDL)

1. rxjava版 安裝若是不要rxjava能夠new Thread但要記住線程裏不要有刷新ui操做
    private void install(final String packageName, final String filePath) {
        Observable.create(new ObservableOnSubscribe<Integer>() {
            @Override
            public void subscribe(ObservableEmitter<Integer> e) throws Exception {
                File file = new File(filePath);
                if (filePath == null || filePath.length() == 0 || file == null) {
                    e.onNext(0);
                    return;
                }
                String[] args = { "pm", "install", "-r", filePath };
                ProcessBuilder processBuilder = new ProcessBuilder(args);
                Process process = null;
                BufferedReader successResult = null;
                BufferedReader errorResult = null;
                StringBuilder successMsg = new StringBuilder();
                StringBuilder errorMsg = new StringBuilder();
                try {
                    process = processBuilder.start();
                    successResult = new BufferedReader(new InputStreamReader(process.getInputStream()));
                    errorResult = new BufferedReader(new InputStreamReader(process.getErrorStream()));
                    String s;
                    while ((s = successResult.readLine()) != null) {
                        successMsg.append(s);
                    }
                    while ((s = errorResult.readLine()) != null) {
                        errorMsg.append(s);
                    }
                } catch (IOException e1) {
                    e1.printStackTrace();
                } finally {
                    try {
                        if (successResult != null) {
                            successResult.close();
                        }
                        if (errorResult != null) {
                            errorResult.close();
                        }
                    } catch (IOException e1) {
                        e1.printStackTrace();
                    }
                    if (process != null) {
                        process.destroy();
                    }
                }
      if (successMsg.toString().contains("Success") || successMsg.toString().contains("success")) {
                    e.onNext(2);
                } else {
                    e.onNext(1);
                }
            }
        }).subscribeOn(Schedulers.newThread())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(new Observer<Integer>() {
                    @Override
                    public void onSubscribe(Disposable d) {

                    }
                    @Override
                    public void onNext(Integer value) {
                        if (value==2) {
                             //安裝成功
                        } else {
                             //安裝錯誤
                        }
                    }

                    @Override
                    public void onError(Throwable e) {
                       //安裝錯誤
                    }

                    @Override
                    public void onComplete() {

                    }
                });
}
2.卸載
    private void uninstall(String packageName) {
        try {
            PackageManager pm = context.getPackageManager();
            Method[] methods = pm!=null?pm.getClass().getDeclaredMethods():null;
            Method mDel = null;
            if (methods != null && methods.length>0) {
                for (Method method : methods) {
                    if (method.getName().toString().equals("deletePackage")) {
                        mDel = method;
                        break;
                    }
                }
            }
            if (mDel != null) {
                mDel.setAccessible(true);
                mDel.invoke(pm,packageName,null,0);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }複製代碼
