SystemInfo returning wrong values on Note3 and newer devices

SystemInfo.systemMemorySize returns negative value (-1784) on Note 3 and SystemInfo.graphicsMemorySize returns value of zero on same. Is there any other way to get the amount of memory available on these devices. Thanks!

 

You could write a plugin for that

I wrote a plugin using this piece of code https://stackoverflow.com/questions/3998713/android-how-do-you-get-total-memory-ram-in-the-device since MemoryInfo requires API 16. Thanks!

 

@bitter I'm using Unity3d 4.3.2f1. I filed a bug using Report a bug inside editor. On a side note here's some explanation about the same : Note3 has 3GByte of RAM and the systemMemorySize is of type 'int'. So the correct size is 2^32 - 1784 * 2^20.

 

Can you share the plugin please? I tried to write a Java class but I ran into the error "java.lang.IllegalStateException: System services not available to Activities before onCreate()" when I try to call the function

This is my Java file

Code (CSharp):

1. package com.DefaultCompany.MemoryTest;
2. import com.unity3d.player.UnityPlayerActivity;
3. import android.os.Bundle;
4. import android.util.Log;
5. import android.os.Bundle;
6. import android.util.Log;
7. import android.app.ActivityManager;
8. import android.app.ActivityManager.MemoryInfo;
9. import androidx.appcompat.app.AppCompatActivity;
10.  
11.  
12. public class MemoryInfoChecker extends UnityPlayerActivity {
13.   protected void onCreate(Bundle savedInstanceState) {
14.     // Calls UnityPlayerActivity.onCreate()
15.     super.onCreate(savedInstanceState);
16.     // Prints debug message to Logcat
17.     Log.d("OverrideActivity", "onCreate called!");
18.   }
19.   public double[] getMemoryInfo() {
20.     ActivityManager activityManager = (ActivityManager ) super.getSystemService("ACTIVITY_SERVICE");
21.     MemoryInfo memoryInfo = new ActivityManager.MemoryInfo();
22.     activityManager.getMemoryInfo(memoryInfo);
23.     double[] values = new double[2];
24.     values[0] = memoryInfo.availMem;
25.     values[1] = memoryInfo.totalMem;
26.     return values;
27.   }
28. }
