Android 静默安装

导言:
由于公司定制设备需要静默安装,而不使用我们熟悉的热更新,目前热更新不能完全代替安装(阿里和腾讯系都不能完全覆盖更新),所以就需要静默安装,而静默安装需要root权限,若需要安装后自动启动就需要android 7.0以下系统才行.

热修复现状:
Sophix和Tinker不支持添加四大组件,Amigo由于阿里收购,不再维护并且支持gradle版本过低,导致好的技术丧失,技术的悲剧

静默安装核心步骤:

//1:判定app是否获取root权限
    public static boolean isRootPermission() {
        try {
            Process process = Runtime.getRuntime().exec("su");
            DataOutputStream os = new DataOutputStream(process.getOutputStream());
            os.writeBytes("ls /data/data/\n");
            os.writeBytes("exit\n");
            os.flush();
            BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            StringBuilder builder = new StringBuilder();
            String line = null;
            while ((line = reader.readLine()) != null) {
                builder.append(line);
                builder.append(System.getProperty("line.separator"));
            }
            String result = builder.toString();
            if (result.contains("com.android.phone")) {
                return true;
            }
        } catch (IOException e) {
            return false;
        }
        return false;
    }


//2:安装apk
    public boolean install(String apkPath) {
        boolean result = false;
        DataOutputStream dataOutputStream = null;
        BufferedReader errorStream = null;
        try {
            Process process = Runtime.getRuntime().exec("su");
            dataOutputStream = new DataOutputStream(process.getOutputStream());
            String command = "pm install -r " + apkPath + "\n";
            dataOutputStream.write(command.getBytes(Charset.forName("utf-8")));
            dataOutputStream.flush();
            dataOutputStream.writeBytes("exit\n");
            dataOutputStream.flush();
            process.waitFor();
            errorStream = new BufferedReader(new InputStreamReader(process.getErrorStream()));
            String msg = "";
            String line;
            while ((line = errorStream.readLine()) != null) {
                msg += line;
            }
            if (!msg.contains("Failure")) {
                result = true;
            }
        } catch (Exception e) {
        } finally {
            try {
                if (dataOutputStream != null) {
                    dataOutputStream.close();
                }
                if (errorStream != null) {
                    errorStream.close();
                }
            } catch (IOException e) {
            }
        }
        return result;
    }

//3:静默安装后需要自动启动,因此就需要注册安装替换静态广播,但是必须是7.0以下才行,因为8.0删除了该静态广播注册的功能
public class OpenApkReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Intent localIntent;
        if (intent.getAction().equals("android.intent.action.PACKAGE_REPLACED")) {
            localIntent = new Intent(context, MainActivity.class);
            localIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(localIntent);
        }
    }
}


//androidmanifest.xml静态广播注册
   
            
                
                
            
        

结束.
