parsing error after launching intent to install apk

So i have a function which downloads and then installs the apk. When the intent launches I get "There was a problem parsing this package." error. However,if i try installing it manually it works fine.
DownloadActivity.java:
public void onClickUpdate(View view) throws IOException {
Toast.makeText(SettingsActivity.this, "Checking for updates", Toast.LENGTH_SHORT).show();
OkHttpClient client = new OkHttpClient.Builder().connectTimeout(10, TimeUnit.SECONDS).writeTimeout(10,TimeUnit.SECONDS).readTimeout(10,TimeUnit.SECONDS).build();
final Request request=new Request.Builder().url("theurl").addHeader("version",version).get().build();
client.newCall(request).enqueue(new Callback() {
#Override
public void onFailure(#NotNull Call call, #NotNull IOException e) {
e.printStackTrace();
}
#Override
public void onResponse(#NotNull Call call, #NotNull Response response) throws IOException {
try {
File sdcard=new File("sdcard/Download");
File file=new File(sdcard,"app-debug.apk");
file.createNewFile();
BufferedSink sink=Okio.buffer(Okio.sink(file));
sink.writeAll(Objects.requireNonNull(response.body()).source());
sink.close();
runOnUiThread(new Runnable() {
#Override
public void run() {
Toast.makeText(SettingsActivity.this, "Installed successfully!", Toast.LENGTH_LONG).show();
try{
Intent intent=new Intent(Intent.ACTION_VIEW);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
Uri uri=Uri.parse("content://"+"sdcard/Download/app-debug.apk");
intent.setDataAndType(uri, "application/vnd.android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);}catch (Exception e){
e.printStackTrace();
}
}
});
} catch (Exception e) {
e.printStackTrace();
}finally {
response.close();
}
}
});
}

Also I did try Android install apk programmatically error - Package Parse error but that did not help at all.
the logs:

I fixed it by adding this:
StrictMode.VmPolicy.Builder builder=new StrictMode.VmPolicy.Builder();
StrictMode.setVmPolicy(builder.build());
builder.detectFileUriExposure;
I don't recommend doing this.
Try wrapping your file URI with content:// instead.

App crashes on resuming by clicking the app icon from menu

App launches normally. When I try to minimize it and reopen through the recent apps history, again it works fine. But when I minimize and try to re open it with the app icon, it crashes.

The stack trace clearly indicates that the call to intent.getData() at line 44 of your MainActivity is returning a null. You should check for the null, and not try to interrogate the Intent if it is null.

You could store string data in a static variable, and then check to see if it's null. If it's null use the static data. I know static variables are frowned upon and you should address the root problem, but this will fix your immediate problem.
static String yourStaticString;
...
String data;
if (intent.getData()==NULL)
{
data = yourStaticString;
}
else
{
if (intent.getData().getLastPathSegment()!=NULL)
{
data = intent.getData().getLastPathSegment();
yourStaticString = data;
} else return;
}

Libgdx - IllegalStateException at unknown location

I am using android studio 1.3, and libgdx 1.6.2 to create a game. I want to incorporate google play services to my game and I have completed everything in one step, because I did it before without problem. However, this time it gave me an exception:
java.lang.IllegalStateException: A fatal developer error has occurred. Check the logs for further information.

So here is what I changed other than adding baseGameUtils (which was sucessfully added).

You need to use <meta-data> inside your <application> tag in the AndroidManifest.

Clear your data and uninstall updates on Google Play Services.
Then, reinstall it.

I looked for answer on stackOverflow, nothing helped.
Anyone knows what's going on?
DataDevice and NFCUtilForeground works good (in other applications).

The android:name attribute in application tag in your manifest file should point to your DataDevice class. Like:
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme"
android:name="your.package.DataDevice">
.........
..........
</application>

Java Android Unhandled exception type IOException and Unhandled exception type ClientProtocolException

In my Android app I'll get the source of a html page. That's my Code: http://pastebin.com/FJyWhVrL It shows me every time by getHtml(); an Unhandled exception type IOException and Unhandled exception type ClientProtocolException. In the manifest file I've set the permission it looks like this:
<uses-sdk android:minSdkVersion="15" />
<uses-permission android:name="android.permission.INTERNET"/>
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >

</intent-filter>
</activity>
</application>
Can someone help me?
Thank you

Those are compile errors. You are calling getHtml, which can throw these two exceptions.
So you need to catch them in your code and do something about it.
button.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
try {
getHtml();
}
catch (IOException e){
// do something
}
catch (ClientProtocolException e){
// do something
}
}
});
