Android O 静默安装

使用pm命令实现静默安装

一.系统签名

1.通过系统中的签名文件,使用命令签名

java -jar signapk.jar platform.x509.pem platform.pk8 app.apk app_signed.apk

2.利用系统中的签名文件生成xxx…keystore,在AS里签名

3.通过ubuntu环境编译，mk文件中设置

LOCAL_CERTIFICATE := platform

out中编译出来的应用就是系统签名后的

具体签名步骤可以参考

系统签名的三种方式

二.在AndroidManife.xml 中添加android:sharedUser

android:sharedUserId="android.uid.system"

三.安装的方法

private static String TAG = "MainActivity"; private File fileDownloads; private File imageFileDirctory; private String path; //安装文件路径 注意FileProvider的使用 //可以参考https://www.jianshu.com/p/47fcd7873f39 private void init() { try { fileDownloads = this.getExternalFilesDir(Environment.DIRECTORY_DOWNLOADS); imageFileDirctory = new File(fileDownloads + "/" + "CPU-Z.apk"); path = imageFileDirctory.getAbsolutePath(); //storage/emulated/0/Android/data/com.fih.storeapp/files/Download/CPU-Z.apk Log.e(TAG, path); } catch (Exception e) { Log.e(TAG, e.getMessage()); } } public static int installSilent(String filePath) { File file = new File(filePath); if (filePath == null || filePath.length() == 0 || file == null || file.length() <= 0 || !file.exists() || !file.isFile()) { return 1; } //pm install -i 'com.fih.mypjdemo' --user 0 //com.fih.app是当前应用的包名，不是安装的包名 String[] args = {"pm", "install", "-i", "com.fih.app", "--user", "0", filePath}; ProcessBuilder processBuilder = new ProcessBuilder(args); Process process = null; BufferedReader successResult = null; BufferedReader errorResult = null; StringBuilder successMsg = new StringBuilder(); StringBuilder errorMsg = new StringBuilder(); int result; 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 e) { e.printStackTrace(); } catch (Exception e) { e.printStackTrace(); } finally { try { if (successResult != null) { successResult.close(); } if (errorResult != null) { errorResult.close(); } } catch (IOException e) { e.printStackTrace(); } if (process != null) { process.destroy(); } } // TODO should add memory is not enough here if (successMsg.toString().contains("Success") || successMsg.toString().contains("success")) { result = 0; } else { result = 2; } Log.e(TAG, "successMsg:" + successMsg + ", ErrorMsg:" + errorMsg); return result; }
