I am trying to turn on the portable Wifi hotspot ON, by referring this link:
how to set advanced settings of android wifihotspot
This is working well on Samsung Galaxy S3 Android v4.4.2.(no issues)
But on other devices with the same or lower Android version, the application crashes and restarts the device.
The code is as follows:

Thus I have the following questions:
I would like to know why is this app behaving normally on Samsung S3
but not on other devices?
How can I fix this issue?
I had the same issue. You must to erase the following code line:
netConfig.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
That works for me in versions 4.1.1, 4.2 and 4.3.
Try this code .I test in android 5.0.1 :
public boolean setHotSpot(String SSID,String passWord){
Method[] mMethods = mWifiManager.getClass().getDeclaredMethods();
for(Method mMethod: mMethods){
if(mMethod.getName().equals("setWifiApEnabled")) {
WifiConfiguration netConfig = new WifiConfiguration();
if(passWord==""){
netConfig.SSID = SSID;
netConfig.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);
netConfig.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
netConfig.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
netConfig.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
}else{
netConfig.SSID = SSID ;
netConfig.preSharedKey = passWord;
netConfig.hiddenSSID = true;
netConfig.status = WifiConfiguration.Status.ENABLED;
netConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
netConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
netConfig.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
netConfig.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
netConfig.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
netConfig.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
netConfig.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
}
try {
mMethod.invoke(mWifiManager, netConfig,false);
mWifiManager.saveConfiguration();
return true;
} catch (Exception e) {
e.getMessage();
}
}
}
return false;
}
Insert this permission in AndroidManifest:
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
If you are using WPA_PSK authentication, you have to specify preSharedKey.
netConfig.preSharedKey = "testPassword";
netConfig.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
Otherwise it will crash and restart the device.

Trying Android development after some time, I am trying to download a zip file from FTP but even after repeat tries, still get FileNotFound Exception when i try to write the file in FileOutputStream. The file clearly exists on local storage as I am printing it 2-3 times (please check output log)

I remember earlier the download used to work like this, but I read some posts about storage access issues, so I updated my manifest appropriately with:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE"/>
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/Theme.MyApplication"
android:requestLegacyExternalStorage="true">
But result is same.
Now I need help in understanding:
Why do I get FileNotFoundException when file exists, as It can be seen printed on screen just before it crashes
Even the Toast which I remember used to work earlier is not working at all in MainActivity.java
Also I need to unzip the downloaded file, if anyone has a better suggestion for a new library or it still works the old way ?

Iam making a weather app but whenever Iam not entering or entering wrong city name in EditText the app crashes even though I have used try and catch blocks for error handling.The below is the java,xml code and the logs where it is showing a runtime error.

I'm try to play a loading animation on my loading screen, and I read somewhere that android doesn't support gifs so either you have to break in into frames and then play it or we can use the Movie class.
Heres the leading activity -

private Socket mSocket;
String you;

String username;

try {
mSocket = IO.socket(Constants.CHAT_SERVER_URL);
} catch (URISyntaxException e) {
throw new RuntimeException(e);
}
}

super.onCreate(icicle);
setContentView(new MYGIFView(getApplicationContext()));

}
}).setNegativeButton("I'll fkin face it",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
}
});
AlertDialog alert = builder.create();
alert.show();
}
}
In the above code I've set content view by passing it an instance of MYGIFView.class -
Heres MYGIFView.class
package com.myapp.mehul.login;
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Movie;
import android.view.View;
import java.io.InputStream;
/**
* Created by mehul on 2/7/16.
*/
public class MYGIFView extends View{
Movie movie,movie1;
InputStream is=null,is1=null;
long moviestart;
public MYGIFView(Context context) {
super(context);
is=context.getResources().openRawResource(+ R.drawable.loading);
movie=Movie.decodeStream(is);
}
#Override
protected void onDraw(Canvas canvas) {
canvas.drawColor(Color.WHITE);
super.onDraw(canvas);
long now=android.os.SystemClock.uptimeMillis();
System.out.println("now="+now);
if (moviestart == 0) { // first time
moviestart = now;
}
System.out.println("\tmoviestart="+moviestart);
int relTime = (int)((now - moviestart) % movie.duration()) ;
System.out.println("time="+relTime+"\treltime="+movie.duration());
movie.setTime(relTime);
movie.draw(canvas,this.getWidth()/2-20,this.getHeight()/2-40);
this.invalidate();
}
}
The loading activity IS creating an instance of MYGIFView.class and it logs the data but then it gives fatal signal 11. I tried to search but I didn't get any answer.

I received a batch for this question which means its being viewed a lot, so I'll answer this question -
What I figured out was the line below was throwing the error -
movie.draw(canvas,this.getWidth()/2-20,this.getHeight()/2-40);
Now the problem is that this error specifically can be caused by lots of reasons, its never a specific reason.. the reason mine wasn't working out was because my device didn't work well with hardware acceleration, so I just had to disable it in the manifest application, like this -
<android:hardwareAccelerated="false">
Now its possible that the reason might not be the same....but the core reason is the same, its memory related, and most chances are its a bug in the firmware of the device or emulator you are testing upon.
In the Manifest set in your activity :
<activity
android:name="LoadingScreen"
android:hardwareAccelerated="false">
</activity>
I got here with the exact same problem but in React Native, so I will put a solution for those who need it too. The error may be triggered by react-native-webview and/or React Navigation. In some cases, like me, you don't want to disable Hardware Acceleration on the whole app, so here's a workaround:
react-native-webview
<WebView
androidHardwareAccelerationDisabled
source={source}
/>
React Navigation 5
<NavigationContainer>
<Stack.Navigator initialRouteName="HomeScreen">
<Stack.Screen
name="HomeScreen"
component={HomeScreen}
options={{
animationEnabled: false,
}}
/>
</Stack.Navigator>
</NavigationContainer>

In your displayBodyTemp() function, you are passing a String and using + to add an arraylist. That is the story.You need to pass a string only. Or override the toString() method of the Arraylist
OR, try this:
displayBodyTemp("Your Body Temperature Readings are:" + text);
