📜 Description

Similar to

sentry-java/sentry-android-core/src/main/java/io/sentry/android/core/ActivityFramesTracker.java

Lines 161 to 172 in a45911f

	final MeasurementValue tfValues =
	new MeasurementValue(frameCounts.totalFrames, MeasurementUnit.NONE);
	final MeasurementValue sfValues =
	new MeasurementValue(frameCounts.slowFrames, MeasurementUnit.NONE);
	final MeasurementValue ffValues =
	new MeasurementValue(frameCounts.frozenFrames, MeasurementUnit.NONE);
	final Map<String, @NotNull MeasurementValue> measurements = new HashMap<>();
	measurements.put(MeasurementValue.KEY_FRAMES_TOTAL, tfValues);
	measurements.put(MeasurementValue.KEY_FRAMES_SLOW, sfValues);
	measurements.put(MeasurementValue.KEY_FRAMES_FROZEN, ffValues);
	activityMeasurements.put(transactionId, measurements);

we want to report slow and frozen frame count for transactions, just like we had before.

It looks like it's actually possible, but as far as I can see no SDK has it implemented yet => getsentry/team-mobile#172
