To measure text beforehand, remove static layout dependency from MeasuredText. Now MeasuredText can compute native measured text by itself and StaticLayout use it for line breaking. This CL introduce one additional JNI method call per paragraph during line breaking but looks negligible cost. Here is a raw performance test result on walleye-userdebug. StaticLayoutPerfTest (median, N=100): createRandom: 7,879,440 -> 7,964,789 (+1.08%) createRandom Balanced: 7,835,192 -> 7,848,151 (+0.17%) TextViewOnMeasurePerfTest (median, N=100): measure_AtMost: 92,599,175 -> 93,027,121 (+0.47%) measure_Exactly: 89,949,922 -> 90,439,886 (+0.54%) measure_Unspecified: 148,645,916 -> 150,047,694 (+0.94%) Bug: 67504091 Test: bit CtsTextTestCases:* Test: bit CtsWidgetTestCases:* Test: bit CtsGraphicsTestCases:* Test: bit FrameworksCoreTests:android.text.StaticLayoutTest Change-Id: Ie932903845645e50cfa0cb428babb31a44babc47
