The problem is when i adjusted the android device system font-size, my user application's font-sizes are changing to device system font-size how to prevent it
The default unit for font size in Android is Scaled Pixels, setting it to DIP or PX will prevent auto scaling.
Tested against v6.0
import { isAndroid } from 'tns-core-modules/platform';
import { TextBase } from 'tns-core-modules/ui/text-base/text-base';
declare var android; // required if tns-platform-declarations is not installed
if (isAndroid) {
TextBase.prototype[require("tns-core-modules/ui/text-base/text-base-common").fontSizeProperty.setNative] = function (value) {
if (!this.formattedText || (typeof value !== "number")) {
if (typeof value === "number") {
this.nativeTextViewProtected.setTextSize(android.util.TypedValue.COMPLEX_UNIT_DIP, value);
}
else {
this.nativeTextViewProtected.setTextSize(android.util.TypedValue.COMPLEX_UNIT_PX, value.nativeSize);
}
}
};
}
Since you are using Angular, you may place this code in main.ts
Or in app module.
