1.在AndroidManifest.xml文件中，添加REQUEST_INSTALL_PACKAGES权限
<uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES"/>
2.在打开安装包的代码中添加**兼容Android 8.0**的代码。
/**
* 打开安装包
*
* @param mContext
* @param fileUri
*/
publicvoidopenAPKFile(Activity mContext, String fileUri) {
DataEmbeddingUtil.dataEmbeddingAPPUpdate(fileUri);
// 核心是下面几句代码
if(null!= fileUri) {
try{
Intent intent = newIntent(Intent.ACTION_VIEW);
File apkFile = newFile(fileUri);
//兼容7.0
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
Uri contentUri = FileProvider.getUriForFile(mContext, mContext.getPackageName() + ".fileProvider", apkFile);
intent.setDataAndType(contentUri, "application/vnd.android.package-archive");
//兼容8.0
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
booleanhasInstallPermission = mContext.getPackageManager().canRequestPackageInstalls();
if(!hasInstallPermission) {
ToastUtil.makeText(MyApplication.getContext(), MyApplication.getContext().getString(R.string.string_install_unknow_apk_note), false);
startInstallPermissionSettingActivity();
return;
}
}
} else{
intent.setDataAndType(Uri.fromFile(apkFile), "application/vnd.android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
}
if(mContext.getPackageManager().queryIntentActivities(intent, 0).size() > 0) {
mContext.startActivity(intent);
}
} catch(Throwable e) {
e.printStackTrace();
DataEmbeddingUtil.dataEmbeddingAPPUpdate(e.toString());
CommonUtils.makeEventToast(MyApplication.getContext(), MyApplication.getContext().getString(R.string.download_hint), false);
}
}
}
/**
* 跳转到设置-允许安装未知来源-页面
*/
@RequiresApi(api = Build.VERSION_CODES.O)
privatevoidstartInstallPermissionSettingActivity() {
//注意这个是8.0新API
Intent intent = newIntent(Settings.ACTION_MANAGE_UNKNOWN_APP_SOURCES);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
mContext.startActivity(intent);
}
