我想要实现自动更新之后马上自动安装,它是本地的所以它不是在应用市场里的。
这是我的代码
public void Update(String apkurl){
try {
URL url= new URL(apkurl);
HttpURLConnection c= (HttpURLConnection) url.openConnection();
c.setRequestMethod("GET");
c.setDoOutput(true);
c.connect();
String PATH= Environment.getExternalStorageDirectory() + "/download/";
File file= new File(PATH);
file.mkdirs();
File outputFile= new File(file, "app.apk");
FileOutputStream fos= new FileOutputStream(outputFile);
InputStream is = c.getInputStream();
byte[] buffer= new byte[1024];
int len1= 0;
while ((len1= is.read(buffer)) != -1) { fos.write(buffer, 0, len1);
}
fos.close();
is.close();
Intent promptInstall= new Intent(Intent.ACTION_VIEW)
.setData(Uri.parse(PATH+"app.apk"))
.setType("application/android.com.app");
startActivity(promptInstall);
} catch (IOException e) {
Toast.makeText(getApplicationContext(), "Update error!", Toast.LENGTH_LONG).show();
}
}
我的权限是INTERNET, WRITE_EXTERNAL_STORAGE, INSTALL_PACKAGES, DELETE_PACKAGES
当网络提示安装加载的时候,引用程序就无法继续运行
所以,是我缺少什么权限还是我的代码不正确,或者有更好的方法来实现吗?
