java 开发语言 android8.0以下静默安装自启动

引入第三方库下载安装包

implementation 'com.ixuea:android-downloader:3.0.0'

下载安装包

private static boolean isdownloadingPack = false; //是否正在下载安装包

if (isdownloadingPack) {

return;

}

File file = new File(Constants.APK_PATH);

//如果文件已存在就先删除

if (file.exists()) {

file.delete();

}

DownloadManager downloadManager = DownloadService.getDownloadManager(getContext().getApplicationContext());

DownloadInfo downloadInfo = new DownloadInfo.Builder().setUrl(安装包网络地址)

.setPath(Constants.APK_PATH)

.build();

downloadInfo.setDownloadListener(new DownloadListener() {

@Override

public void onStart() {

LogUtils.d("开始下载安装包");

isdownloadingPack = true;

}

@Override

public void onWaited() {

}

@Override

public void onPaused() {

}

@Override

public void onDownloading(long progress, long size) {

long l = progress * 100 / size;

LogUtils.d("正在下载安装包：" + l + "% - 总大小： " + size / 1024 / 1024 + "MB");

}

@Override

public void onRemoved() {

}

@Override

public void onDownloadSuccess() {

LogUtils.d("下载成功");

DeviceUtils.getInstance().installPackage(Constants.APK_PATH, true);

LogUtils.d("安装成功");

}

@Override

public void onDownloadFailed(DownloadException e) {

LogUtils.d("下载失败" + e);

isdownloadingPack = false;

}

});

downloadManager.download(downloadInfo);

manifest文件注册静态广播

UpdateRestartReceiver.java

public class UpdateRestartReceiver extends BroadcastReceiver {

@Override

public void onReceive(Context context, Intent intent) {

String action = intent.getAction();

String localPkgName = context.getPackageName();

//取得MyReceiver所在的App的包名

Uri data = intent.getData();

String installedPkgName = data.getSchemeSpecificPart();

//取得安装的Apk的包名，只在该app覆盖安装后自启动

if ((action.equals(Intent.ACTION_PACKAGE_ADDED) || action.equals(Intent.ACTION_PACKAGE_REPLACED)) && installedPkgName.equals(localPkgName)) {

/**

* 启动activity

*/

安装方法

public String installSilently(String path) {

Log.d("lozie", "path" + path);

// 通过命令行来安装APK

String[] args = {"pm", "install", "-r", path};

String result = "";

// 创建一个操作系统进程并执行命令行操作

ProcessBuilder processBuilder = new ProcessBuilder(args);

Process process = null;

InputStream errIs = null;

InputStream inIs = null;

try {

int read = -1;

process = processBuilder.start();

errIs = process.getErrorStream();

while ((read = errIs.read()) != -1) {

}

baos.write('\n');

inIs = process.getInputStream();

while ((read = inIs.read()) != -1) {

baos.write(read);

}

byte[] data = baos.toByteArray();

Log.d("lozie", "result" + result);

} catch (IOException e) {

e.printStackTrace();
