以编程方式在Android N中安装应用程序
以编程方式在Android N中安装应用程序
提问于 2018-01-16 04:16:00
我想在我的应用程序中安装一个apk，我正在使用这种方法，但是我总是得到下面列出的错误：
代码
File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/test.apk");
Uri fileUri = Uri.fromFile(file);
if (Build.VERSION.SDK_INT >= 24) {
fileUri = FileProvider.getUriForFile(DLActivity.this, "codenevisha.com.apps.bartarinapp.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_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(intent);这是我的清单：
<?xml version="1.0" encoding="utf-8"?>

</activity>
<activity android:name=".activity.DLActivity">
</activity>
</application>
</manifest>我使用了这个path.xml文件：
<external-files-path
name="share"
path="."/> 但是当我运行我的应用程序时，得到了这个错误：

我测试了下面的代码。
在Menifest中添加以下权限
<uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />下面是安装包的代码
//// TODO: 1/16/18 Check the external storage permission
File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/test.apk");
Uri fileUri = Uri.fromFile(file);
if (Build.VERSION.SDK_INT >= 24) {
String packageId = getApplicationContext().getPackageName();
fileUri = FileProvider.getUriForFile(MainActivity.this, packageId + ".files", file);
}
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.putExtra(Intent.EXTRA_NOT_UNKNOWN_SOURCE, true);
intent.setDataAndType(fileUri, "application/vnd.android" + ".package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(intent);Menifest中的提供程序
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.files"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_paths" />
</provider>file_paths.xml
<paths>
<external-path name="external" path="/"/>

您的FileProvider配置错误。您的FileProvider元数据需要<external-path>元素，但您没有。参见the documentation。
