android静默安装

如果是做指定设备开发的,一般设备都有root,这个时候就可以用shell命令安装了,安装代码如下(filePath 为安装包路径):

 String[] cmd0 = {"pm install -r " + filePath + "\n"};
                ShellUtil.execCommand(cmd0, true);

ShellUtil工具类:

public class ShellUtil {

    private final static String COMMAND_SU = "su";
    private final static String COMMAND_SH = "sh";
    private final static String COMMAND_EXIT = "exit\n";
    private final static String COMMAND_LINE_END = "\n";

    public static class CommandResult {
        public int result = -1;
        public String errorMsg;
        public String successMsg;
    }

    public static ShellUtil.CommandResult execCommand(String[] commands, boolean isRoot) {
        ShellUtil.CommandResult commandResult = new ShellUtil.CommandResult();
        if (commands == null || commands.length == 0) return commandResult;
        Process process = null;
        DataOutputStream os = null;
        BufferedReader successResult = null;
        BufferedReader errorResult = null;
        StringBuilder successMsg = null;
        StringBuilder errorMsg = null;
        try {
            process = Runtime.getRuntime().exec(isRoot ? COMMAND_SU : COMMAND_SH);
            os = new DataOutputStream(process.getOutputStream());
            for (String command : commands) {
                if (command != null) {
                    os.write(command.getBytes());
                    os.writeBytes(COMMAND_LINE_END);
                    os.flush();
                }
            }
            os.writeBytes(COMMAND_EXIT);
            os.flush();
            commandResult.result = process.waitFor();
            //获取错误信息
            successMsg = new StringBuilder();
            errorMsg = new StringBuilder();
            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);
            commandResult.successMsg = successMsg.toString();
            commandResult.errorMsg = errorMsg.toString();
//            Log.d(TAG, commandResult.result + " | " + commandResult.successMsg
//                    + " | " + commandResult.errorMsg);
        } catch (IOException e) {
            String errmsg = e.getMessage();
            if (errmsg != null) {
                Log.e("util", errmsg);
            } else {
                e.printStackTrace();
            }
        } catch (Exception e) {
            String errmsg = e.getMessage();
            if (errmsg != null) {
                Log.e("util", errmsg);
            } else {
                e.printStackTrace();
            }
        } finally {
            try {
                if (os != null) os.close();
                if (successResult != null) successResult.close();
                if (errorResult != null) errorResult.close();
            } catch (IOException e) {
                String errmsg = e.getMessage();
                if (errmsg != null) {
                    Log.e("util", errmsg);
                } else {
                    e.printStackTrace();
                }
            }
            if (process != null) process.destroy();
        }
        return commandResult;
    }
}

安装完之后再监听系统的安装广播,自动打开APP:

public class BootReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(final Context context, final Intent intent) {
       if (Intent.ACTION_PACKAGE_ADDED.equals(intent.getAction()) || Intent.ACTION_PACKAGE_REPLACED.equals(intent.getAction())) {
            String localPkgName = context.getPackageName();
            //取得MyReceiver所在的App的包名
            Uri data = intent.getData();
            String installedPkgName = data.getSchemeSpecificPart();
            if (installedPkgName.equals(localPkgName)) {
                Intent bootIntent = context
                        .getPackageManager()
                        .getLaunchIntentForPackage(context.getPackageName());
                bootIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                context.startActivity(bootIntent);
            }
        }
    }
}

在AndroidManifest.xml文件注册静态广播:

  <receiver android:name=".BootReceiver">
            <intent-filter>
                <action android:name="android.intent.action.PACKAGE_ADDED" />
                <action android:name="android.intent.action.PACKAGE_REPLACED" />
                <action android:name="android.intent.action.PACKAGE_REMOVED" />
                <data android:scheme="package" />
            </intent-filter>
        </receiver>

这样就大功告成啦!

shell功能是很强大的,很多功能都能用shell命令实现,比如修改设备时间,以太网IP,设备重启等
