How to programmatically get the IMSI-Number in Android

I tried the following code: 

private String getImsi() {
   TelephonyManager mTelephonyMgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
   return mTelephonyMgr.getSubscriberId();
}

<uses-permission android:name='android.permission.READ_PHONE_STATE' />

But it only returns null.

Is there any other way to obtain the IMSI with java in android?

The following solution works only for system applications:

    private String getIMSI(){
        telephonyManager = (TelephonyManager) getSystemService(this.TELEPHONY_SERVICE);
        return telephonyManager.getSubscriberId();
    }

In AndroidManifest.xml add permissions:

    <uses-permission android:name="android.permission.READ_PHONE_STATE"/>
    <uses-permission android:name="android.permission.READ_PRIVILEGED_PHONE_STATE" />

The second permission is marked as system

Works in Android 9 (API 28).

String imei = android.os.SystemProperties.get(android.telephony.TelephonyProperties.PROPERTY_IMSI);

with permission 

 android.permission.READ_PHONE_STATE

Since SystemProperties is a hidden class in Android, you can access it with reflection:

/**
 * Get the value for the given key.
 * @return an empty string if the key isn't found
 */
public static String get(Context context, String key) {
    String ret = "";

    try {
        ClassLoader cl = context.getClassLoader(); 
        @SuppressWarnings("rawtypes")
        Class SystemProperties = cl.loadClass("android.os.SystemProperties");

        //Parameters Types
        @SuppressWarnings("rawtypes")
        Class[] paramTypes= new Class[1];
        paramTypes[0]= String.class;

        Method get = SystemProperties.getMethod("get", paramTypes);

        //Parameters
        Object[] params = new Object[1];
        params[0] = new String(key);

        ret = (String) get.invoke(SystemProperties, params);
    } catch(Exception e) {
        ret = "";
        //TODO : Error handling
    }

    return ret;
}

Did you add this permission in the manifest?

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

Edit: ok, try use this one:

String myIMSI =
android.os.SystemProperties.get(android.telephony.TelephonyProperties.PROPERTY_IMSI);

SystemProperties it's an hidden class. try to check here: https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/os/SystemProperties.java
