    <p>I have an indicator on my application to display the network type (2G or 3G or 4G) but after getting the network type, how do I know what speed category it should be in?</p> <p>I know how to detect the network type:</p> <pre><code>private TelephonyManager telephonyManager; telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE); CurrentNetworkType = telephonyManager.getNetworkType(); </code></pre> <p>Given the possible return values:</p> <pre><code>// public static final int NETWORK_TYPE_1xRTT // Since: API Level 4 // Current network is 1xRTT // Constant Value: 7 (0x00000007) // // public static final int NETWORK_TYPE_CDMA // Since: API Level 4 // Current network is CDMA: Either IS95A or IS95B // Constant Value: 4 (0x00000004) // // public static final int NETWORK_TYPE_EDGE // Since: API Level 1 // Current network is EDGE // Constant Value: 2 (0x00000002) // // public static final int NETWORK_TYPE_EHRPD // Since: API Level 11 // Current network is eHRPD // Constant Value: 14 (0x0000000e) // // public static final int NETWORK_TYPE_EVDO_0 // Since: API Level 4 // Current network is EVDO revision 0 // Constant Value: 5 (0x00000005) // // public static final int NETWORK_TYPE_EVDO_A // Since: API Level 4 // Current network is EVDO revision A // Constant Value: 6 (0x00000006) // // public static final int NETWORK_TYPE_EVDO_B // Since: API Level 9 // Current network is EVDO revision B // Constant Value: 12 (0x0000000c) // // public static final int NETWORK_TYPE_GPRS // Since: API Level 1 // Current network is GPRS // Constant Value: 1 (0x00000001) // // public static final int NETWORK_TYPE_HSDPA // Since: API Level 5 // Current network is HSDPA // Constant Value: 8 (0x00000008) // // public static final int NETWORK_TYPE_HSPA // Since: API Level 5 // Current network is HSPA // Constant Value: 10 (0x0000000a) // // public static final int NETWORK_TYPE_HSPAP // Since: API Level 13 // Current network is HSPA+ // Constant Value: 15 (0x0000000f) // // public static final int NETWORK_TYPE_HSUPA // Since: API Level 5 // Current network is HSUPA // Constant Value: 9 (0x00000009) // // public static final int NETWORK_TYPE_IDEN // Since: API Level 8 // Current network is iDen // Constant Value: 11 (0x0000000b) // // public static final int NETWORK_TYPE_LTE // Since: API Level 11 // Current network is LTE // Constant Value: 13 (0x0000000d) // // public static final int NETWORK_TYPE_UMTS // Since: API Level 1 // Current network is UMTS // Constant Value: 3 (0x00000003) // // public static final int NETWORK_TYPE_UNKNOWN // Since: API Level 1 // Network type is unknown // Constant Value: 0 (0x00000000) </code></pre> <p>I would consider LTE to be 4G, but which of these are really considered 3G? Anything else I would consider 2G.</p> <p>So where do you draw the line between 3G or not 3G? </p> <p>Update: I found another relevant answer at <a href="https://stackoverflow.com/a/8548926/949577">https://stackoverflow.com/a/8548926/949577</a> It uses ConnectivityManager() to get type and subtype and then classifies the subtype as either fast or not. I don't know if using ConnectivityManager() is a better approach then using TelephonyManager () since they both appear able to return the network type.</p> <p>Also I found a link that compares wireless data standards at <a href="http://en.wikipedia.org/wiki/Comparison_of_wireless_data_standards" rel="noreferrer">http://en.wikipedia.org/wiki/Comparison_of_wireless_data_standards</a>.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
