以编程方式在 Android 7 / api24 中安装 apk
Programmatically install an apk in Android 7 / api24
我正在尝试让我的应用程序自动安装 apk。这适用于 api<24。但是对于 24,它是失败的。 Android 已实施额外的安全措施:
For apps targeting Android 7.0, the Android framework enforces the StrictMode API policy that prohibits exposing file:// URIs outside your app. If an intent containing a file URI leaves your app, the app fails with a FileUriExposedException exception.
所以我尝试了这个:
Uri myuri;
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.N){
myuri = Uri.parse("file://"+outapk);
} else {
File o = new File(outapk);
myuri = FileProvider.getUriForFile(con, con.getApplicationContext().getPackageName() + ".provider", o);
}
Intent promptInstall = new Intent(Intent.ACTION_VIEW).setDataAndType(myuri,"application/vnd.android.package-archive");
con.startActivity(promptInstall);
但出现致命异常:
com.android.packageinstaller "Caused by: java.lang.SecurityException: Permission Denial: opening provider android.support.v4.content.FileProvider from ProcessRecord{b42ee8a 6826:com.android.packageinstaller/u0a15} (pid=6826, uid=10015) that is not exported from uid 10066".
我的清单中有 export=true。
问题似乎是 packageinstaller 不能使用 content:// uri。
是否有任何方法可以让应用程序以编程方式安装带有 api24 的 apk?
Are there any ways to allow an app to progammatically install an apk with api24?
将 addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
添加到您的 promptInstall
设置中,以授予对内容的读取权限。
I have export=true in my manifest.
不在您的 FileProvider
上,因为那样会导致您的应用程序崩溃。
The problem seems to be that packageinstaller cannot use a content:// uri.
不,问题是您没有授予包安装程序读取该 Uri
的权限。如果软件包安装程序无法使用 content
方案,您将获得 ActivityNotFoundException
.
不过请注意,只有 Android 7.0 包安装程序才开始支持 content
。 Android 的早期版本必须使用 file
.
在 res/xml
添加文件 -> provider_paths.xml
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="external_files" path="."/>
</paths>
在AndroidManifest.xml
中添加此代码
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.example.provider" <-- change this with your package name
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths"/>
</provider>
运行 此代码用于安装您的应用或打开
public void installApk(String file) {
Uri uri = FileProvider.getUriForFile(context, BuildConfig.APPLICATION_ID + ".provider",new File(file));
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(uri, "application/vnd.android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
context.startActivity(intent);
}
对于奥利奥,
在 AndroidManifest
中添加权限
<uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES"/>
对于Oreo,在AndroidManifast中添加权限(否则它只是默默地失败)
<uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES"/>
现在添加到您的清单
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths"/>
</provider>
在xml目录中添加...
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="external_files" path="." /></paths>
然后在您需要的地方使用这些代码。
File directory = Environment.getExternalStoragePublicDirectory("myapp_folder");
File file = new File(directory, "myapp.apk"); // assume refers to "sdcard/myapp_folder/myapp.apk"
Uri fileUri = Uri.fromFile(file); //for Build.VERSION.SDK_INT <= 24
if (Build.VERSION.SDK_INT >= 24) {
fileUri = FileProvider.getUriForFile(context, BuildConfig.APPLICATION_ID + ".provider", file);
}
Intent intent = new Intent(Intent.ACTION_VIEW, fileUri);
intent.putExtra(Intent.EXTRA_NOT_UNKNOWN_SOURCE, true);
intent.setDataAndType(fileUri, "application/vnd.android.package-archive");
intent.setFlags( Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); //dont forget add this line
context.startActivity(intent);
}
只需执行以下步骤:
1- 将以下权限添加到清单中:
<uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES"/>
2- 将提供程序添加到清单(作为子应用程序标记):
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="tatcomputer.ir.libraryapp.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/paths"/>
</provider>
3- 添加 paths.xml 到 xml 目录:
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<files-path name="files" path="." />
<external-files-path name="external_files" path="." />
<external-path name="external_files" path="." />
<cache-path name="cached_files" path="." />
<external-cache-path name="cached_files" path="." />
</paths>
4- 使用以下代码显示安装 apk 页面(请注意,在我的例子中,apk 位于我的 phone 的根目录中,名为 tmp.apk:
String root = Environment.getExternalStorageDirectory().toString();
Uri fileUri24 = FileProvider.getUriForFile(App.applicationContext, BuildConfig.APPLICATION_ID + ".provider", new File(root + "/tmp.apk"));
Uri fileUri = Uri.fromFile(new File(root + "/tmp.apk"));
Intent intent = new Intent(Intent.ACTION_VIEW);
if (Build.VERSION.SDK_INT >= 24)
intent.setDataAndType(fileUri24, "application/vnd.android.package-archive");
else intent.setDataAndType(fileUri, "application/vnd.android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
App.applicationContext.startActivity(intent);
这是我找到的解决方案
val newFile = File(dirPath, "$fileNameWithoutExtn.apk")
var fileUri = Uri.fromFile(newFile)
//use the fileProvider to get the downloaded from sdcard
if (Build.VERSION.SDK_INT >= 24) {
fileUri = FileProvider.getUriForFile(this@SettingAcitivity, applicationContext.packageName + ".provider", newFile)
val intent=Intent(Intent.ACTION_VIEW)
intent.setDataAndType(fileUri, "application/vnd.android.package-archive")
intent.flags = Intent.FLAG_GRANT_READ_URI_PERMISSION
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
startActivity(intent)
}else{
newFile.setReadable(true, false)
val intent = Intent(Intent.ACTION_VIEW)
intent.flags = Intent.FLAG_ACTIVITY_CLEAR_TOP or Intent.FLAG_ACTIVITY_NEW_TASK
intent.setDataAndType(fileUri, "application/vnd.android.package-archive")
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
startActivity(intent)
}
并写入清单
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/paths"/>
并设置权限
<uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES" />
在 xml 中,文件夹路径将为
<paths>
<external-path
name="external_files"
path="." />
</paths>
自动安装 Apk
Intent intent1 = new Intent(Intent.ACTION_INSTALL_PACKAGE);
intent1.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent1.setDataAndType(Uri.fromFile(new File(Environment.getExternalStorageDirectory() + "/download/" +filename)), "application/vnd.android.package-archive");
intent1.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
就我而言 android 8.0 问题出在
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
